I have both a 2001 and 1999 XJ (4DR, manual, 4.0L engine). The rocker panels on the driver's side of both cars are rusted through--common problem, I think--and I'm plotting a repair. It's not something I can do myself (don't know how to weld), and I'm willing to spend some money to get this done right. I see a wide variety of 3rd-party solutions to this problem, and wonder what the readers of this board might recommend who've actually done it. Thanks.
