i have a customer who needs 68 front fenders and extensions and his "buddy" told him not to buy anything but GM Fenders.
so i told him i woudl see what i could find,
i am doing my customer service thing
If you think GM fenders are going to fit any better than repros you could be in for a big surprise and will be taking a sledge hammer to them too! It all depends when they were produced and later ones fit just as bad as anything you can find, quality control was not any better at the GM stamping plants on cars they weren't building anymore.
I remember a time when 2nd gen Firebird front fenders were so bad that people would ask for reproductions.
