A '95 MC and Booster is around $150 new/reman. I think $10 each for thread adapters. That's not too bad. Still not sure what I'll do but better brakes are in the cards. I don't think I need hydro boost. The Jeep brakes pretty well right now. Just want a bit more bite. I also might consider doing a Teraflex Disc conversion since they still make a kit that fits the XJ44 and it's reasonably cheap as well.
I am interested in this kit as well; not so much for the improvement in braking, but more because of the maintenance free operation that disc brakes offer, especially considering the abuse we put drum brakes through with all the mud here. This would also help me solve my e-brake problem, I think (at least, with a new cable, which I saw are like $18 online...)
