First things first - have to fix this mess -
Cab mounts were replaced on both sides from where the material was good (not all the way across the cab, but a decent portion from the rockers in towards the center) For the floor panel replacement I didn't bother buying repop panels as the worst area was a flat section with a drop off towards the rocker. I would have just ended up cutting up new panels and then still having to fabricate a bunch, it was just as easy to just patch everything together - it's not a show truck, just meant to be a daily driver.
A bit of grinding to clean up the ugly stich welds and some seam sealer to make sure it's all water tight
I put back a seat belt mount where it was rotten on the passenger side (rot was cut out below the mount on the drivers side) however I wasn't going to be using these mounts after upgrading the seats.
