Passenger side speedometer Muncie's outsell Pontiac ones 10 to 1 or more. Pontiac also had a long tailhousing/mainshaft application. I've never heard of anyone needing the long shaft version and I've followed closely since the mid 90's. I agree with you if the gears are all good and the countershaft bore isn't blown out on the case. Ive paid $800-1000 plenty of times for certain used ones like the one i described in my prior post. Usually 10 spline input 69 dated Norwood stamped units. Finding used Muncie's in good condition is like trying to find a needle in a hay stack. They are so badly beaten the case is shot as well as at least one speed gear, both synchro assemblies, and the shift forks are almost always worn too much to be used in a remanufactured trans. I've remanufactred plenty of "rebuilt" muncie's. Big difference between the two terms imo.
