Yesterday I went to a parts guy to get the small bracket that joins the 2 hood panels at the back. He had 3 hoods, 2 chevy's & 1 GMC. The GMC hood latch & nose area of the hood was very different in shape than the chevy hoods. But the back braces were the same in both chevy & GMC. Both Chevy Hoods looked Identical. As far as I know here in Canada, the AD Trucks from the 50's were only made in Oshawa, Ontario. Perhaps the Canadian made trucks were more concistant because they would have all been made on the same press? Just an observation.
