My rear bumper in perspective from above. It attaches by the original bumper frame bolts, plus 3 more on each side for the hitch load-distribution arms, plus one more on each top for good measure.
I have revised the center storage compartment door so it's much simpler, stronger, & easier to remove.

This bumper ended up weighing ~180# empty (when it was on the '83 frame).
