I just got my XJ back from BPI Fab after they test fitted the new XJ rear bumper and tire carrier. Check these things out, they are very stout and smooth. BPI Fab guy at BPI Fab said that the bumpers are all the same from 1984-2002.
They were fabbing the side panel which replaces the stock plastic corners that is more slim line. These guys have a
sweet shop and fab up some of the best bumpers I’ve ever seen, there prices are even less then most all their
competitors. He said they are in full swing to start selling the rear bumper so give them a call
