slip

Time for my yearly rocker panel patch job on the 96 XJ and I've decided to look into the slip on rocker panels I've been told about. What I'm wondering is if there are actual rocker panels specifically manufactured to be slipped over existing rocker panels, or do people just get another...

Edit. Looking for the best slip yoke eliminator kit & CV driveshaft to throw onto this girl. She dropped her rear driveshaft in the road. Brands or suggested dealers? Thanks a million!
