Does anyone know where to find discontinued parts? I've tried everywhere online. I'm looking for the rear tumbler seat Bumper Seat Cushion for my 1997 Wrangler TJ Sport. It's missing one and the seat rattles everytime I hit a bump and annoys me something fierce. The part number is 04874151. The part is basically nothing more than a threaded bolt and nut that goes through the hole on the base of the rear tumbler seat. It has a rubber bumper ring on the end of it that acts as a cushion. Any help in locating one of these would be greatly appreciated.
