Do a search for slip yolk. Speedster93b had one put in his driveshaft and that is the best idea to do if your concerned about your driveshaft being to long. It will surprise you how much his slip moves
wow yeah his shaft moves alot. mine only move a 1/4 of an inch through travel. i was just wondering if anybody else had them shortened cause if not you should go check your tranny seal mine was completly gone
