The engine wasn't the concern. But knowing that the GMC engine is longer which puts the cross member farther out is good to know because it has a direct effect on the front sheet metal. Or it helps me understand why the front sheet metal isn't as easy to interchange.

The whole reason for these questions is because I'm looking at a '50 GMC 1 ton that needs body work. The engine runs fine so that's not a concern right now. I'm just researching as to the availabilty of body parts and whats interchangable.
