You buy a floor and fit it in or cut sheet metal to weld in a new floor. Really not sure what you are doing? Cardboard template is usually the best start. Are you patching. Did the owner cut out the spot welds or hack it all upi? FYI, to save money, sections are available from $30-$70.

Well, I tried to upload, but of course it exceeded the 300mb limit.. Email me, [email protected], and I will send it to you or go to Chevrolet Heritage and download the complete manual for free.. Good luck, Thirdcoast
