Man, it was brought to my attention I put the shoes on backwards on the passenger rear wheel. Haha. Oh well, gotta redo it.
The other night I welded in my 5-point harness mounting tabs. They're 1/4" thick and I used the 6"x 6"x 1/8" plates supplied with my roll cage, that I didn't use because it's welded to the frame, to reinforce where I mounted them. Should be plenty strong considering the flooring is 14 gauge and everything is all welded into one another (body, flooring, cage, frame, etc.).
