I have a 58 Buick it needs panel repair where rear trunk body mounts are, was wondering what odds are readily available aftermarket 57 chevy trunk panels could be adapted to repair area ,style of trunk looks similar
Really doubt it. Buick Special and Century bodies shared some components with Oldsmobile. Super and Roadmaster bodies hand some commonality with Cadillac. Not sure but think than Chevy and Pontiac are closer. Buick replacement sheet metal other than floor pans usually comes from junk yard or fabricated. Great cars but not easy to find parts for. I can speak from experience!
I really think it won't work, but you can use some raw steel to make your own patch panels. I had a 55 pontiac parts car when I was building my 55 chevy, the floor was completely different. But the doors and windows were the same.
they are different but rear back part where body mounts are looks close, any one able to get measurement center to center of these body mounts
