GMC Restoration-Historical Help

[GMC_Aaron]

I recently bought a 1972 GMC Super Custom and I want to learn everything about it, but I'm confused because I can't find any info. on it like I could a Chevy. Why is this? I know the trucks are virtually identical, but does GMC have any seperate literature such as sales brochures, etc.? I chose to buy a GMC because I liked the grille design better. I know that alot of the aftermarket parts, manuals, etc. reference both GMC and Chevy, but did GMC have seperate literature when they rolled off the floor? How can I get it. What would my truck have as far as literature, manuals, tags, etc. when it was sold? What is the story behind GMC and Chevy? Why is there so much more out there for Chevy and very little for GMC. Please help. I really want to get invloved in the history of my truck. Feel free to e-mail me with any insight@ motostud_5@netzero.net
