Thankyou.
CCOT
Bought probably 4 years ago and sitting on the shelf waiting for this to happen.
Fit was OK.
The lip they had bent didn't reach all the way to the tailgate opening edge. I had to cut the lip off and make the splice in about 3/4" in from the tailgate edge (see pix).
Otherwise happy with them.
I had previously taken measurements off a stock clean rig that helped me set them at the right height as mine and been hacked, Along with my rockers.
In hindsight given the amount of time I am spending patching and the condition of my wheel wells and rear floor, the idea of full rear half tub replacement probably would have got me out ahead (If I was billing my time hourly, and assuming it fit reasonably okay) for those considering something similar...
The rear sill is 2.5 x 2.5 x 3/16 angle x 51" long, with a 2.5 x 3/16 flat welded to make a C channel with some vertical support added inside and nuts welded in for the tailgate hinges.
I needed the two and a half inches to reach back to non rusted floorboard, and a two and a half inch height was right to support the body on new body mounts.
The top of the wheel wells is 1/8" plate, cut to the curve of the quarter panel with a cardboard template, and a 1/8 x 3/4" lip added to attach the quarter skin.
I have a custom 4x4 labs family roll cage that sits flat on a mounting plate on top of the wheelwell so I don't need the stock roll cage mounts. I will add additional bracing as needed.
