Nothing earth-shattering, but I got the rear bumper mounted. Ended up stumbling upon a set of 73-80 bumper brackets at the PNP. If you know squares, you know the center brackets are rare as hen's teeth. They bolted up to the 81+ bumper fine, they just needed a 1/2"x1" steel spacer in the top mounting bolt between the bumper and the bracket. Also ended up moving the bumper in about 1-1/4", by drilling some new mounting holes in the frame.
It's not a cool-guy smoothie bumper, but it didn't cost me $150 either. Pulled it off a Suburban at the PNP and only paid $25 for it. Pulled the plastic rub pad off and bolted 'er up. Beats the clunky old step bumper that was on it, I think.
