if you were going to pay 500 for another one it would maby cost you that to rebuild it. all of the special tools you can do with out. Or what i did was take my input drum in and had a tranny shop put the teflon seals on for me. I also took every thing that needed springs to be compressed and had them do it. They did not even charge me for it. Just call around to some local tranny shops until you find one that is willing to help you out.
