If I were doing it I would find the pedals, mechanism, etc. from another car. Then if going with a 4spd I would source from another car as well. If you want a five or six speed you have the various Tremec suppliers, Richmond, Mcloed or even Jerico or Nash. Passon Performance claims they will be providing a 5 spd that is a direct bolt in to replace an A833 but I don't think they have shipped one for several months. Both Passon Performance and Brewers performance can provide complete conversion kits and the Tremec suppliers can provide kits if you car is equipped with pedals for a stick.
