Buddy -
Those parts are from Authentic Parts Company
http://www.restoration-world-chevy-parts.com/history.htm The floor is about $495, the firewall is around $200, I think the cab back is around $150.
The parts are factory spec and accurate in all regards except I am not sure on the metal thickness.
I bought the firewall along with a bunch of other little parts for several different projects.
Work continues to go nuts, I get a couple of hours a week tops working on truck related projects. The suburban 292 motor is coming together - I need to buy motor mounts to set it in the frame next.
