Stock clutch fork yes but modified slightly. Very slightly. It has to be slit and welded. Just to create more of a bend.

Cost for us was about $200. But thats only cause we do all the fab work and the tranny was only 60 from a friend. Havent priced them in the j-yards.

You have to fab an adapter from the tranny to the housing, thats what the 1 inch steel is for.

It was done on a smallblock in a chally.

I have heard that the 6 speed is close but I havent gotten my hands on one, yet.
