I’d spent a fair bit of time stretching the door edges to fit the opening a lot better, but had noticed that the inner part of the frame was all over the place from where the roof had been chopped.

I decided it was beyond hope, and just chopped it out. The replacement panel was easy enough, but welding it back in wasn’t so easy. I decided to hang the cab from the roof by one of the hinges with the other side on the floor.

With it up like that I could stand in the hole where the transmission cover goes, and reach up to weld the frame. Welding was better but I burnt my head a lot with sparks!. Quick smooth with a flap disc and I was back where I started minus the wrinkles and dents.
