    You must be so pleased with that effort Justin. You deserve that excellent result. I never ever thought , it would involve so much work to correct it all to your exacting standard. Mind you, without the Cellette jig and a known 356 in good condition to refer back to so many factory measurements ,it could have been so much more difficult for you. I hope many have followed this thread to become fully aware, of just how complicated a repair can be on a damaged 356 front end !

    Left lower brace in further solidifying the new nose into its final position.
    Click image for larger version  Name:	IMG_1432.jpg Views:	0 Size:	215.5 KB ID:	114801 Before it went on for good I had to hammer flat those incorrect rolled edges.
    Click image for larger version  Name:	IMG_1433.jpg Views:	0 Size:	231.2 KB ID:	114802 After a bit of checking and rechecking for square and even then the end of it was welded to the bracket mount. Had it at the needed length on the last try so no further adjustments there. I did move the fender tab upward a touch so the approach angle matched the other side.
    Click image for larger version  Name:	IMG_1434.jpg Views:	0 Size:	218.7 KB ID:	114803 Wanted the brace runs to appear symmetrical through the windows of the horn grill openings. Not a big deal but it was just bugging me until I made that quick simple adjustment.
    Click image for larger version  Name:	IMG_1435.jpg Views:	0 Size:	232.4 KB ID:	114804 It took some doing but this nose is now squared and evenly mounted with the chassis; spaced and angled to match my reference car and finally gaped and matched to the edge of this hood. A lot of ducks to get in a row for sure.
    Click image for larger version  Name:	IMG_1438.jpg Views:	0 Size:	239.3 KB ID:	114805 Now onto stitching it back up with the trough starting with the leading edge first.

    Thanks for looking.

    Every job you do on this car needs thought before you weld !! Just as well you do that Justin.

    Adding in the fender braces:
    Click image for larger version  Name:	IMG_1396.jpg Views:	0 Size:	215.8 KB ID:	114789 Approximate distance from the battery box wall to the edge of the fender on my undamaged original reference car is 16 3/4 inches. This nose in its relaxed state is just shy of 18 inches.
    Click image for larger version  Name:	IMG_1397.jpg Views:	0 Size:	225.4 KB ID:	114790 I would normally like to set that outer bolt in the center position but with the preliminary measurement I'm getting the edges of this nose must do nothing but come inward.
    Click image for larger version  Name:	IMG_1398.jpg Views:	0 Size:	228.9 KB ID:	114791 So I'm going to shorten this brace a little more so the bolt starts the tangs inner edge giving me full adjustment to push the bodywork inwards. Chalked up my table here and ready hammer a little more of the shoulder down flat allowing the brace to mount inward a little more.
    Click image for larger version  Name:	IMG_1399.jpg Views:	0 Size:	225.7 KB ID:	114792 First mock with the reshortened brace now locating the bolt at the inner edge of the slot giving me full range to come inward. Brace sitting square upper conduit slipping in nicely so far.
    Click image for larger version  Name:	IMG_1430.jpg Views:	0 Size:	182.7 KB ID:	114793 Brace attached to the bumper mount. Gas welded along the sides as originally. Every undisturbed original I've removed were also welded and attached internally. With the conduit out of my I was able to get in there and catch the folded shoulders and attach them to the mount as the factory did. Moving onto the left side.

    Thanks for looking!

ID:	114783 Now that the nose is centered with the chassis and gapped to the hood I can begin tying it in further with confidence.

    Fender braces and headlight buckets up next.
    Thanks for looking!

    Tacking the rest of the skin up the sides of trough.
    Click image for larger version  Name:	IMG_1387.jpg Views:	0 Size:	207.1 KB ID:	114775 Went up the left side first by carefully shaping a filler strip to bridge the gap where the trough edge needs to be and where it once was at the skins edge. All tacked in with my 3MM+ gap and leveled off from the hood's edge. Of course this will change slightly as the welding continues so I'm only committing to tack welds for a while.
    Click image for larger version  Name:	IMG_1388.jpg Views:	0 Size:	204.2 KB ID:	114776 Then onto the left side; and again this damn lower corner still wants to sit low and not carry the line off the edge of the hood. I think this problem is a combination of some slight residual damage on the hood and maybe some tightness with the new skins profile. Either way most the give has to come from the skin side as the substructure will begin asserting itself if I try heeling the edge over more than a mm or two.
    Click image for larger version  Name:	IMG_1389.jpg Views:	3 Size:	183.4 KB ID:	114777 Before any tack welding along this side the skin had to be raised to the needed level with the hoods edge. Began adding paint sticks in behind it to get the needed height.
    Click image for larger version  Name:	IMG_1390.jpg Views:	3 Size:	197.7 KB ID:	114778 This compensation height now made the vertical lip too short along this troubling run so an extension strip was added.
    Click image for larger version  Name:	IMG_1391.jpg Views:	3 Size:	210.5 KB ID:	114779 Extension strip shaved down to needed height against the edge of the hood and then the right side was tacked locking in that shape. Not perfect but its all well within striking distance.

    Hi Roy, The cellette bench was so important for dialing the chassis but like you said, now its really providing critical confirmation as the nose is being fitted. The hood is really tricky and I'm not surprised that the gaps changed on you a little as the years have rolled by. You'd be amazed at how badly a previously nice fitting hood will behave just by simply removing the rubber seal. The hood really just floats in the latched position if you really think about it. Even the plunger on the hood side, if there is slight warped or walk in it you can manipulate the gap left or right just by rotating it. A lot of variables and the gap I'm trying to establish now is most certainly going to change on me as the welding progresses. I just have to make sure I've left myself enough wiggle room to compensate for that eventuality. Justin

    Justin this hood fitment has been so interesting where you have to get the perfect 'gap' to body correct. What a good idea to check the rubber seal at this stage and again the Cellete helps to confirm your methods along with the wooden sticks as you have no special fixtures. So much to consider to get this gap correct. I make a point now which I expect you are fully aware of but its never been wrtitten down in any book I have on gap clearance settings. So don't laugh if I mention it below:-

    I have removed my bonnet lid a number of times over these 55 years of me opening it. But a while ago I noticed on the left side the gap had increased to the right hand side. The increase in gap on the left side occured on the last 3/4 of the lid towards the front nose. I have never hit anything and it puzzled me a lot. I thought maybe the L/side fender had sort of moved or dropped in some way. It was annoying ! So I decided to go through the bonnet lid instalation again by the factory manual. I released the two nuts on the hinge arms each side and checked the also the 4 year old bonnet rubber seal . All hinges worked well no apparent problems at all. I then went through the procedure of resetting as per the book and I had the same clearance issue!

    So... I then tried a thought I had to correct it. I left the two L/H hinge bolts tight but lightlyloosened the two right side hinge bolts. Then I lightly pushed the bonnet over to the left side and still holding this position I tightened the two R/side hinge nuts. When lowering the lid it had corrected everything back to even gap clearance left and right !!

    This did surprise me that it corrected this extra 2mm or so error in the bad area only. This was done maybe a year ago no problems with the hinges it just solved my problem of getting an even gap all around.

    Nose fitment continued:
    Click image for larger version  Name:	IMG_1380.jpg Views:	0 Size:	190.2 KB ID:	114767 Hardest part of locating this nose to the chassis is that I don't have dedicated holding jigs. I figured out a way around that this time around. Measuring the distance from the battery box to the noses' edge on my original undamaged reference car I was able to make these standoffs out of paint sticks. The right thickness now holds the nose at just the right distance away from the box while also supporting its weight with a quick clamping. This solved a lot of placement challenges all at once. Now onto both centering and leveling the skin to the chassis.
    Click image for larger version  Name:	IMG_1383.jpg Views:	0 Size:	226.6 KB ID:	114768 After several rounds of measuring, clamping and remeasuring again I finally had the nose centered and leveled to the chassis. Grill openings are equal distance from the battery box walls. For additional confirmation the horn grill openings reveal a near identical amount of the cellett fixture.
    Click image for larger version  Name:	IMG_1384.jpg Views:	0 Size:	231.3 KB ID:	114769 Comfortable enough to begin tack welding it to the trough's leading edge from the center outward.
    Click image for larger version  Name:	IMG_1385.jpg Views:	0 Size:	193.2 KB ID:	114770 I am still dealing with the profile misalignment at the center of the hood with the center profile of the nose but I determined that I couldn't worry about it right now. I need to fully set and mount the rest of the nose first then I can come back and clean these profile discrepancies.

ID:	114771 Continued working my way up the sides fishing the skin's edge up level with the hood as it went. Again note the noses' bottom leading edge with the cellette's holding fixture. This is about as square and even as I could have hoped for.

    Thanks for looking!

    Justin

    Back to refitting the nose.
    Click image for larger version  Name:	IMG_1376 - Copy.jpg Views:	0 Size:	223.2 KB ID:	114760 Not there yet but I wanted to begin introducing the hood seal to plan for any future fitment issues.
    Click image for larger version  Name:	IMG_1377.jpg Views:	0 Size:	192.0 KB ID:	114761 And of course it stopped the hood well short of latch engagement. The left side run sits a bit high, so this and the thickness of sheet metal screw heads were the obvious culprits with this initial clearance issue. Again not quite there yet but this is critical aspect that need consideration as it goes.
    Click image for larger version  Name:	IMG_1379.jpg Views:	0 Size:	194.5 KB ID:	114762 Right side 3mm+ gap and shape with the edge of the hood re-established.
    Click image for larger version  Name:	IMG_1378.jpg Views:	0 Size:	196.2 KB ID:	114763 With the right side set the left side ran too tight against the hood. I had to reopen one relief cut and add in another to gain the distance and shape with this side of the hood. All set here.

    Thank you very much Roy! Yes, there are a lot of curve balls that gets thrown your way through this process. The trick is to started things in the middle or as neutral as possible to give yourself an out in anticipation of these slight variances as it goes. Justin
