So, I decided to go with a roll pan. I know, I know not on a 4x4. Rear bumper was bent and rusty so it had to go. I wasn't having much luck finding a straight replacement bumper at any of the yards. Found a couple on C/L but they were asking way too much. Couple pics of the install.
Bumper was pushed into the quarter panel a bit.
Fitting up the pan.
I chose to bolt the pan on.
