Frame Measurement Madness

Did you do the cowl already?

David, I did. As you would expect, the factory upper & lower cowl were shot. This car was a Non-AC car. I pulled off the top cowl and patched the lower. The top-hat was good, so reused that. I purchased a 71 donor coupe a few years back that had AC and use it's lower cowl driver-side vent-delete sheet metal to patch and plug the Convertible's factory driver vent location. I use the donor's top cowl and patched it's trouble spots. It was in better shape than the Vert's.

I was just looking at something last night that's concerning me. Where the lower cowl meets and is welded to the A-Piller, there is mild swelling and rust. I really don't want to pull all this apart, would be  a LOT of work. It's structurally sound, but worried what will happen over time. Wondering if there's a way to seal it an prevent further rust. Thoughts??

Any rust that is present will only get worse with time. Fix it properly, which means pulling it apart again, removing the rust, primering, and re-welding.

I just went through this same measurement issue yesterday. I had two different spec sheets with different numbers. 11.74" is not correct. 15.03" is the correct number.

Since you're car is already that naked it;s better to do it right the first time, you don't wanna go there again later on!

I hear you. I'm just bummed that I have to pull all that apart after all that good work. Ug. But, no one to blame but me. At least there's a lot more new stamped metal available than there was when I started this journey. The only issue is the currently available Cowl is Without AC. I did a lot of work to convert this car to factory AC, including moving all the factory brackets and plugging the driver side vent hole with the factory sheet metal blank from my donor. Oh well.

I agree go ahead and cut it out and repair.
On switching from non air to air. The Dynacor would be easy to close the hole I would think.
I see you did not remove the helmet shaped piece that is on firewall under the fender well. That cleared the blower motor with no air is not present on air car.
It will be a while before you put heater box in but I suggest you add a barrier to keep the mice out in the future. I put wire mess in there and also under the cowl vents and put ss scrubber pads in the cowl drains.

David, great info! I didn’t even notice the helmet missing in the AC car. I can fix that. Thx a ton!

Steve, that’s interesting info. If you look at my red line drawing in my original post, I was getting about 15.6". Do we have any other sources for info/confirmation?

If you follow the link in post #3 the second drawing shows the 15.03 measurement. I had a copy of both drawings when I was measuring my car.

I used these measurements to mount my car to a frame table. All of the measurements came out good except the front bumper mount hole. The bumper hole measured 12.2" to the center of the welded nut. The sheets have measurements of 11.91 and 12.38. I still have to fabricate mounts to attach the front of the table to the strut rod crossmember.
