Nice and warm yesterday after work, so I got my little homemade kick panel patches glued in, and filled a hole. The screws are just there to hold it while the adhesive cures. They'll come out and all the little holes will be sealed up.
I also got the studs ground off the back of the cab. Next step is to haul it to the body shop to get the corner welded in.
I'm seriously considering making a panel to fit in the corners so the floor is flush there, no pockets to hold crap and make it rust. Then I'd just leave the area where the cab support meets it unsealed for drainage, or even open it up somemore to allow cleaning. Any thoughts from the board?
