Ebay. There are several on there now. Real easy to install. I know they can be done without pressing the trunnion pin out, but I have a press and that's how I prefer to do it. Only thing I wish they'd make different is where the large strap goes around the boot. There's no rib to keep it from sliding off and down on the boot. There's a rib on the side facing the trunnion housing, but none on the other side, so if you're not careful, the strap will slide off. The small strap on the drive shaft side has ribs on both sides so it stays put. I WAS going to service the entire joint, but it is in very good condition, so I just replaced the torn boot.
