      • Upper trunk floor under tank repair.
        Click image for larger version  Name:	IMG_7864.JPG Views:	0 Size:	537.2 KB ID:	111760 I was going to begin fitting the front half of the floor pan but....
        Click image for larger version  Name:	IMG_7899.JPG Views:	0 Size:	573.7 KB ID:	111761 But this car has some upper trunk floor rot so I decided now would be the best time to address that while I have open access to the underside of it.
        Click image for larger version  Name:	IMG_7900.JPG Views:	0 Size:	503.9 KB ID:	111762 This being a coupe and with both longitudinal members repaired structural integrity is secure enough to remove this sub-frame jig. Now is the time as its in my way for those under dash repairs to the trunk floor.
        Click image for larger version  Name:	image_64699.jpg Views:	3 Size:	475.7 KB ID:	111763 Subframe now removed giving the clearest shot at the underside of the needed repairs.
        Click image for larger version  Name:	image_64700.jpg Views:	3 Size:	444.0 KB ID:	111764 Most of the rust damage is to the left side but both upper corners have rust. I know they make this panel new but this one is very savable and besides it would be far more work and time to replace this panel when you consider all the accessory brackets and attachments on the underside of this panel. Patch repairs coming up next.

        Thanks for looking!

          Click image for larger version  Name:	IMG_7906.JPG Views:	0 Size:	511.9 KB ID:	111797 At the floor I decided to make the break under the reinforcement plate to both conceal and support the eventual weld joint.

          Click image for larger version  Name:	IMG_7909.JPG Views:	0 Size:	454.4 KB ID:	111800 Then it as onto cutting and carefully removing the upper corner. Its pretty intricate and layered in through here so I had to take some time to drill a few spot welds and carefully unpeel this onion to get this old piece out intact as its needed to provide the pattern for the new piece that has to be fabricated.

              Click image for larger version  Name:	IMG_7925.JPG Views:	0 Size:	595.2 KB ID:	111830 Because I'm flipping it over the reliefs are now mirrored and on the wrong side in relation to one another. The skinny rib will have to be cut and moved to the other side of the big one.

This shoulder runs down hill and fades as it moves downward witch puts a bit of a curve ball in there. As you can these corner rusted out too; not as severe and without the complication of a trunk release arch but it will need some unpeeling and repair.

I had to add the 90 back in just to be able to test fit and my angle was of course off ever so slightly throwing the whole part off. It took 4 attempts of bending and re-straightening to get that sucker to fit right, I was getting worried about metal fatigue. BTW turning that corner down in the step was a bridge too far. I had it bright orange and it still tore apart.

                              • Justin, this needs a more than a few words to say how well you have done one this part of the repair. Really exceptional effort to get that all looking as original. I have followed this repair every step of the way and you should be proud of yourself. For any one not ever having attempted this type of work as I have said before so many times ,you make the fabrication of new sections look easy when that is not the case. It takes ingenuity to find and use, metal forming items that will work. I was for the early part of my working life a press toolmaker, all those difficult shapes were machined on to the punch and die and its not easy to replicate those items manually to make it look original. Likewise, you have to understand when the forming is almost beyond what equipment you have at hand.

                                So its looking good my friend !

                                  Hello Roy, Thank you for that really nice and thoughtful comment. You're right I had to do some hunting to find various shaped items around my shop that were going to give me a close enough shape to hammer form into. I seem to just squeak by with what I have on hand. If the shapes are small and complicated enough, as these were I'm hard pressed to make it in one piece though that is my intent; but a relief cut and weld is usually the only way forward most times. A dedicated press and die would have been quite a luxury. Thanks once again for your keen and thoughtful observations. Stay well! Justin
