This is how you put on the rear QJ or Bumper without dropping the gas tank every time. 7/16 14 threaded rod and a coupler bolted to the rear body. Heat shrink on the rod where it contacts the body and a rubber washer. The last standoff that holds the guard is a custom made polished stainless piece with 7/16 14 on one end and 1/2 20 on the other so the guard will bolt on. Yes you have to end wrench it but that beats dropping the gas tank.
