I gotta good deal with an Ironworks style shop who will custom fab what Im guessing is going to be a new four piece long replacement.Im thinking since my floorboard is rotted along the seems on the inner rockers by the seat mounts I would make the first piece enclose this to the outers and the other piece 90 degrees to mount from the undercarriage to this piece..I can get this in any thickness..I know its not factory or after market piece but If I had some good measurements I can have the steel made for $120...Anybody have any measurements laying around????Thanks

if you still have somewhat of a structure in those spots, making a template would be better and easier, the parts are not going to be simple such as 3x4x6
