I installed an All Pro bumper on the FJ about 3 months. I the instructions, it mentions that you have to bend a certain AC line for the bumper to clear. After about 3 months of normal driving, the aluminium ac line rubbing against the steel bumper developed a hole. I would advise all owners with All Pro bumpers to check to make sure that their AC lines are not rubbing against their bumpers & take steps to make sure this does not happen to them. Just wanted people not to make the same mistake I did.
