One of the rear drums on my rig is missing the parking brake spreader bar. (Like the one pictured below.) Parts stores seem to think TJs don't have these in their brakes, so they've been no help. I found a suggestion that it might be Dorman 21158 but I want to be sure before I order one. Also, is it safe to drive with it missing? I assume it will mainly make the parking brake non-functional on the side missing this piece.
