when you are mixing and matching various parts from various sources, you cut down your ability to cross-shop based on price.
just be sure your pilot bearing is specced to fit the prolite flywheel, and the trhowout bearing is specced to fit the act clutch bits...and the only ppl who know this for sure are prolite and act! Ask them directly, if not you are in the running for "Nummah of the Month."
so what if you have to spend a few bucks more than ebay, what really sucks is tearing the car apart only to find you don't have the right parts...the inconvenience factor will make you sorry you tried cheap out here and there on little stuff. don't axe how I learnt this the Very Hard Way!
