This Rokmen rear bumper is a PITA to install. You have to pull off the rear body mounts, Remove the rear skid plate bolts, loosen the front bolts and yank on it w/o having the tank fall down. Remove the 4 carriage bolts, notch out the crossmember 3"x4" on both sides, kind of a PITA . slide the bumper on. Install the 4 new carriage bolts. MAJOR PITA!, fish for the tank strap bolts and reconnect, finesse 4 bolts into holes that you can BARELY get at. If I had to do it again, I'd just drop the tank completely. Spent the whole day just fitting it into place prior to prep and paint.
