I used a WIX 46398 (from a 1995 Acura Integra) to have a paper cone filter on my MJ. Something work looking at and would at least get you going in the right direction.
Ive had issues with their throw out bearings being very "crunchy" when spinning. I've stopped buying them and have gone with the Luk bearing the last few times.
I am in the market for one. But, I can't, currently, justify that price. If you're willing to negotiate and come down some, then I would be inclined to purchase. If not, I understand.
