Finally tore into the k5 project- Looks like the front floor is solid, front cab supports are shot, but major concern is the rear floor/bed area. Plans are to replace cab supports/all body mounts before taking the top off, do all the measuring and then remove the top. My main question is searching for a replacement rear floor. Was planning on 1/8" Steel diamond plate sheet stock. I also was toying with the idea of removing the inner/outer quarter panels as two assemblies, repairing the rot and remounting them. Anybody have any tips, advice, or warnings? Why buy it if you can build it better? All Give Some. Some gave all. God bless the fallen Brothers in the FDNY.
