no matter what anybody says it is always cheaper to do it yourself if your handy and have time to research your parts. if you go to moparts.com under tech archives in manual and clutches. and look for cheap tremec 600 install alot of useful info. I started getting parts for my build. tranny tko 500 $850, pilot bushing custom made from two pilot bearings $30, throwout bearing $50, by the time I am all done I will be into it for like 1500 installed alot cheaper then 3500
