No way I'd get a Richmond. Three friends with very bad experiences. Get a TKO, TKO500 or TKO600, Lakewood bell and look real hard for the pedal assembly and linkages. If you do find pedals but no linkages, you can also go with a hydraulic thow out bearing. Plenty of room for TKO's in 71-73's. Best place to find pedals is probably vintage-mustang.com in classifieds, Might get lucky here though. Dark horse performance or Modern drive line has all you need (other than pedals).
