I have a 34 Chevy Master 2 door sedan that I am wanting to buildup. The first issue I must address is the wood framing of the body. It is completely rotted and missing a lot of pieces. The floor is made almost completely of wood and the wood is what actually bolts to the frame. That wood is totally rotted and withered almost to nothing. The body is loose at the bottom behind the doors, I can move the body panels behind the doors in and out, and I can lift the body off the frame with ease.

I am going to replace all the wood with metal. The most obvious place to start is to make a new subframe for the floor of the body.

I need the measurements for the bottom of the body. I'm not sure where the measurements need to be taken. The mounting brakets that are on the body and screw to the original wood floor frame are there and solidly mounted to the body. That seems to be a good place to measure side to side.

When I build the metal framing for the doors and body, what is the best way to attatch the body and door skins to it? Should I use round tubing?

I know I have a long, hard project ahead of me, but I am confident that I can do it. I just need some good advise and measurements for replacing the wooden floor structure with metal. It wouldn't be so bad if the original wood was still there for me to copy, but it is mostly gone.

Any advise is greatly appriciated!!!!!!!!
