Factory lightweight hood

I bought one of these for my 73 duster and the actual outer skin was all dented and in bad shape but I got it at a good price and was able to take a good hood and switch inner structures... The steal on steal was spotlighted together and I had to drill those out. But the steel and aluminum had some weird crimped pinch fits.. when I put the feather duster innerstructure in the regular duster outer skin I just used a few aluminum rivets...
