Hey there. Are you buying the pre-assembled version, or are you going to put it together yourself? I am in need of a conversion too...my car was originally a disc brake car that drums were put on for some unknown reason. Everything at the top is still for a disc brake car, and all I need is everything at the wheels. No booster, proportioning valve, etc. If you don't buy it pre-assembled, how difficult is it to assemble yourself? Is a press needed for anything? Thanks so much for any reply. Winston
