Floor Pan Replacement - GM A-body

[twertsy]

First, I'm by no means a pro. I purchased a very rough '70 GTO as my "guinea pig" project for a first time complete frame off resto. I'm touring the car so I'm not concerned with originality. It needs the entire floor pan, including trunk. My question deals with maintaining the integrity of the vehicle while doing this. They sell a complete floor pan (minus trunk) complete with crossmembers/floor supports. However, the car is on a rotisserie and I'm concerned with stressing the remainder of the vehicle. Do I need to do some bracing before cutting out the existing floor pan/braces? Should I take it off the rotisserie and perhaps do this while on the lift.....or body cart? Or, should I not purchase the complete floor pan and replace each section individually? To complicate it further, I'm also replacing the rockers.

I can't be of much help other than leading you to thread on Team Chevelle in the "Restoration Corner" section entitled "1970 Convertible Restoration". Tom shows details throughout his restoration including replacing floors, trunk, rockers and just about everything else on the car.

Wow.....and I thought the Goat was rusted. Not nearly as bad as that one. My floor is quite a bit better, but still needs replacing, and my trunk pan is gone. My issue is it appears he kept it on the frame (for the most part) while doing these repairs. My frame is off to blast/powder currently. I'm assuming I shouldn't attempt any of this while on the rotisserie.

Without seeing the floor or trunk area it's hard to make an acessment of what it needs. My 2 cent advise though is if you're doing a full floor replacement it should be sitting on the frame with the frame mts in the correct location. Without that, you won't know if the pan is going to line up with the frame for sure. I think you'll want to put the bolts in as you go and pull them to torque specs too as on an A body, that can effect your gaps.
The AMK full floor is very nice, but correct placement in relation to the frame mts is a must. JMHO

One more thing; Should I have it blasted before repairing or after?
