Glenwood, thank you for the complement.
If you haven’t already completed fabrication on the upper cowl. Use as much of the Sherman upper cowl piece as you can. If I had to do it again, I would cut the windshield wiper hole out of the OEM piece and weld it into the Sherman piece. Then make the Sherman piece fit the lower cowl. A lot less welding.
It was a pain in the rear end welding to the old thinner (due to rusting) factory piece. Even though the original piece was clean and prepped before welding. There was not enough metal to step onto while welding. A hole would blow thru the old metal. So I ended up with some booger welds. Both sides of the piece ended up getting welded.
I sanded thru the metal while trying to smooth everything out. Which means more welding. Sometimes I think, maybe I should have Tig welded the piece, but I don’t know if I could have gotten the old metal clean enough without getting porosity in the weld.
Jay, thank you for the complement.
Even with the rust issues, the cowl you sold me gave me something to work with. Older cars, due to lack of rust proofing on the underside of a panel, will rust from the inside out. The 67-72 Chevrolet and GMC truck are notorious for rusting from the inside out. I have personally been down that road.
For the picture hounds out there:
The areas circled in yellow, are the areas that have shrunk due to welding. It is like looking across a wavy ocean. I have tried hammer on dolly, to stretch these areas, but it doesn't want to cooperate. Does anyone (body men) out there following this thread have any suggestions?
The hole at the leading edge started as a little pin hole. I stuck an awl thru it to check thickness, I continued sticking the awl thru and ended up with the above slot. This hole is currently welded and re sanded.
