  • Wall removal:

    Click image for larger version  Name:	image_65545.jpg Views:	3 Size:	474.2 KB ID:	113012 Engine compartment trimmed out next.
    Click image for larger version  Name:	image_65546.jpg Views:	3 Size:	591.5 KB ID:	113013 Lots of trimming and modifications before this new panel will go but its a nice start.
    Click image for larger version  Name:	image_65547.jpg Views:	3 Size:	498.8 KB ID:	113014 The new rib embossments are light and weak so I'll be defining them deeper to more closely match this original and the right hand side.
    Click image for larger version  Name:	image_65548.jpg Views:	3 Size:	591.4 KB ID:	113015 Now onto the real work of cleaning out the remains of the original wall and getting the area ready to accept the new panel. BTW: this shot really lays bare as to how light these cars are actually constructed. This wall removal really breaks the illusion of substantial and stout quarter panel unit. Its no wonder that these car wad up so quickly and easily.

    Clean up and wall prep begin.

    Thanks for looking!

    • Begin perimeter clean up:
      Click image for larger version  Name:	IMG_9034.jpg Views:	0 Size:	473.3 KB ID:	113018 First trial fit. A long ways to go before this is ready.
      Click image for larger version  Name:	IMG_9037.jpg Views:	0 Size:	477.2 KB ID:	113019 The base of the quarter window arch overlaps the lower closing wall flange so this will be the first layer of the onion to be peeled. Works out fine as it also gives me the opportunity address that rusted area along its pinch seam.
      Click image for larger version  Name:	IMG_9039.jpg Views:	0 Size:	525.6 KB ID:	113020 As far as I need to go. This gets me past the flange rust and clears the path to the closing wall remains. The rubber drain tube that once attached to that metal spout gave up years ago allowing the water to run directly over this area eventually rotting it out.
      Click image for larger version  Name:	IMG_9040.jpg Views:	0 Size:	439.0 KB ID:	113021 Onto drilling out the spots and small gas welds along the bottom of the quarter window opening to get this horizontal run out
      Click image for larger version  Name:	IMG_9041.jpg Views:	0 Size:	461.4 KB ID:	113022 Most of this old base run removed and now stripped back down to the body skin side flange. Chasing the rest of it down into the engine compartment then down the sides after that.

      Thanks for looking.

      • Sail panel and engine compartment flange cleanup:
        Click image for larger version  Name:	IMG_9046.jpg Views:	0 Size:	497.3 KB ID:	113027 Carefully grinding thin and peeling up the remaining spot welded strip. Drilling the spot welds not an option as its attached directly to the exterior body skin. Extra care taken not to damage the surface during removal. This continued right on through into the engine compartment .
        Click image for larger version  Name:	IMG_9047.jpg Views:	0 Size:	486.1 KB ID:	113028 Last flange remnants cleaned and this run now ready to accept the new panel.
        Click image for larger version  Name:	IMG_9049.jpg Views:	0 Size:	477.2 KB ID:	113029 Now onto removing this vertical lap joint along the engine compartment wall.
        Click image for larger version  Name:	IMG_9050.jpg Views:	0 Size:	490.4 KB ID:	113030 Its a double row of tightly spaced spots welds so Grinding and peeling was the best shot at preserving the flange underneath.
        Click image for larger version  Name:	image_65559.jpg Views:	3 Size:	606.8 KB ID:	113031 Cleaned and just about ready to accept a new panel. To my relief only one small breach to backfill on this mating flange. Still have to clean and break it free along the chassis flange as the new panel is joint will slip in under this old one along that flange but not ready to cross that bridge just yet. Moving forward to the lock post to begin cleaning the flange strip remains along there next.

        Thanks for looking,

        • Its not often you see this particular repair taking place maybe a bit frightening to even start it. I wonder how many have not gone down this rusty road when they really should have?

            It is a big piece Roy and I can see were it could look a lot scarier than it really is. At this point its just a really involved process of cleaning up all the attachment points around the perimeter. Then there is the fitment of a new reproduction panel. I already knew what this entailed which is why I did everything in my power to save the other side.

            Click image for larger version  Name:	image_65574.jpg Views:	3 Size:	569.7 KB ID:	113058 I could not get the lap joint to release cleanly at the chassis flange. A lot of spot welds and the flange is very rusty and weak there. A very bad combination if you're trying to take it apart. One thing I've noticed through the years is that its very common to find two badly rusted panels with factory spot welds still refusing to give up. Great news for the rest of the car I suppose...

            Click image for larger version  Name:	image_65577.jpg Views:	3 Size:	510.2 KB ID:	113061 I was hoping to get this junction apart cleanly but I ended up cutting and peeling up the layers that comprised it. As you can see the base flange was too rusty to get aggressive with. The forward section on the other hand was cleaning up nicely with a wire wheel.

            Thanks for looking.

            • Begin new panel prep:
              Click image for larger version  Name:	IMG_9079.jpg Views:	0 Size:	632.5 KB ID:	113063 I'm now down to the last of the flange remains along the back side of the striker post. I'd had it with grinding and peeling for the moment so I took a break began some prep work on the new closing wall.
              Click image for larger version  Name:	IMG_9080.jpg Views:	0 Size:	416.8 KB ID:	113064 The three rib impressions are very weak and shallow compared to what was there originally. Not a big but deal but I want it match more closely to the other side of the car. Starting with the shortest one first, its clamped to my table at an angle so the rib surface rests flush against the table with my hammer form strip positioned inside of the relief shape.
              Click image for larger version  Name:	IMG_9083.jpg Views:	0 Size:	452.8 KB ID:	113065 Heated and the shoulders pecked down to the table drawing the rib up higher or deeper (depending on what side you're looking at) around the hammer form strip.

This photo highlights how weak the provided draw down shape were.

                Click image for larger version  Name:	IMG_9103.jpg Views:	0 Size:	451.8 KB ID:	113071 It of course doesn't fit even close before the flanged edges begin to wedge themselves into the car.
                Click image for larger version  Name:	IMG_9099.jpg Views:	0 Size:	502.7 KB ID:	113072 The closing flanges will need a lot of shaping and tweeking before they'll interlock with the car allowing the panel to seat into its correct position.
                Click image for larger version  Name:	IMG_9102.jpg Views:	0 Size:	561.9 KB ID:	113073 But with each series of trims and adjustments it eventually fits better and better. That next...

                • Justin 100% effort to get those 3 ribs looking correct. Anyone with real experience looking at that area years from now will not be thinking that panels been off ! But to a beginner just starting on their welding experiences better to start on something simple. How you could easily lose your confidence because that job was not easy whatever you might say.
                  Well done indeed!

                    Thank you Roy, I just couldn't leave those as the panel would scream reproduction whenever someone who knows what their looking at poked their head up into this fender well. Its getting closer by the session but a lot of loose ends yet before it goes in for good. Thanks again! Justin

                • New panel fitment continues:
                  Click image for larger version  Name:	IMG_9125.jpg Views:	0 Size:	523.3 KB ID:	113096 After a bit of manipulation and several tries I finally got the new panel to slide into basic position.
                  Click image for larger version  Name:	IMG_9123.jpg Views:	0 Size:	449.0 KB ID:	113097 The key was slipping the rear of the new panel in front of the bulkhead wall flange. It put up a fight of course but I eventually won. Stepped flange of this new section contoured and lined up surprisingly well against the sail panel of the body.
                  Click image for larger version  Name:	IMG_9124.jpg Views:	0 Size:	449.3 KB ID:	113098 Wasn't all good new of course. While this rearward portion is up against the body its current width is holding the remaining flange run at the base of the quarter window flange from mating up tightly. Its also cut short at the transition to the window flange.
                  Click image for larger version  Name:	IMG_9125.jpg Views:	0 Size:	523.3 KB ID:	113099 All that aside its still a very promising initial fit and is much better than I was expecting. Even the ribs where placed in about the right spot in relation to sight makers on the chassis when compared to the other side.

                  • New panel top flange fit and adjustments:
                    Click image for larger version  Name:	IMG_9134.jpg Views:	0 Size:	466.5 KB ID:	113102 Again the flange run fitment between the quarter window and this new panel will be the baseline. Everything else will be made to follow in behind. The rearward section along the sail panel will be hammered back out and re-bent to suit once I have forward fitment I'm after, this will also allow me to reposition that relief cut ahead the quarter window to close up that hole. Another adjustment will be along that 90 degree right above the ribs. Originals were only a soft gentle role versus this hard 90 so this run will be softened.
                    Click image for larger version  Name:	IMG_9136.jpg Views:	0 Size:	502.3 KB ID:	113103 Soften that turn here.
                    Click image for larger version  Name:	IMG_9137.jpg Views:	0 Size:	532.0 KB ID:	113104 Rearward portion of the flange that mates against the body flattened back out here. Will reinstall it once to suit once I have the wall dialed in.
                    Click image for larger version  Name:	IMG_9138.jpg Views:	0 Size:	487.0 KB ID:	113105 Back to test fitting. Quarter window flange and panel now fitting up with that wider rear section flattened and out of the way. Now it was it was onto the final forward and aft position of the new panel.
                    Click image for larger version  Name:	IMG_9143.jpg Views:	0 Size:	323.8 KB ID:	113106 Which meant I now had to go back and finish cleaning off the last bit of the original closing wall flange along the back of the lock post. As you can see its solid run of spot welds so grinding and peeling only. Reutter didn't want these two coming apart again. This whole repair is a bit unusual in that if you're replacing the closing panel the lock post is usually cooked as well so normally you're not having to deal with this old flange joint. I'm lucky...

                      Click image for larger version  Name:	image_65610.jpg Views:	3 Size:	506.6 KB ID:	113109 Entire run along the lock post finally clean and ready to accept the new panel. So glad to have this stage of the preparation completed.

This upper leading corner I'm pounding in tight to keep it out of my way as the fitment continues. Once I've got it this will be relaxed back out to close up tightly against the body.
                      Click image for larger version  Name:	IMG_9152.jpg Views:	0 Size:	551.4 KB ID:	113111 I have these two flanges running about as even and uniform as I can for now.
                      Click image for larger version  Name:	IMG_9153.jpg Views:	0 Size:	518.7 KB ID:	113112 While that was going on I was dialing in the best fitment against the lock post. The flange swings a little wide towards the bottom here so it was temporarily bent out of the way for now but I'll adjust that out as it continues. Working next on getting that sweep (gap)along the chassis mated up tight. It doesn't just fit up against it there. It fights and has to be stretched and pulled into that curve; all the while taking care not to lose my initial flange fitment. A lot going on at once.

                      Thanks for looking!

                      • Nice work as always Justin. This is an area that is tough to get to behind the outer skin. It real helps to be able to turn the car on its side and upside down. This is where a rotisserie pays big dividends.

                          Thanks again Scott! Having the ability to turn the car over during rust repairs is a luxury that cannot be overstated. Even with the car upside down as shown in the photo above this panel's installation and prep is still trying my patience. Hope you're still making some headway on your project. Justin
