did he not have a full body then to sell? I understand he has a salvage yard also.
Also, you might check in dallas area for some of the major salvage yards, as we have 1 or 2 here, and one local gm salvage yard sells full tahoe, suburban and hummer bodies. I saw what they did and it was pretty neat. They have a contract with gm and they have to video tape the dismanteling of each vehicle, then they can sell the body and the complete rolling chassis, but the same person can't buy both pieces. With access to dallas and houston I'd bet you have something there.
If you would like me to I can call my buddy at the gm salvage and see if he has any connections (which I'm sure they do since they are part of a huge network) and see what he comes up with.
are you looking for a bare body? full body with wiring etc. or what, and what is something of that magnitude going for?
