I would like to convert from an automatic to a stick, preferably a 5 speed with overdrive. my car is a 72 and I am running a 468 with turbo 400 and 456 gears. I am looking for a strong trans that would require minimum floor mods, the floor is painted on the underside. Does anyone have a reccomendation? I have considered the new muncie m22 if I cant find a 5 speed that fits my existing tunnel.
