I’m listing this for a friend, we both have 50 years experience in motorcycles, but are not car guys. He inherited his late brothers estate with cars and parts and this transmission was in that lot. From the limited research we’ve done the following information is what we believe to be true, but if something is not accurate, please let me know what I will change it. Believe this is pre 1969 Muncie 4 speed transmission M22, inside is clean with no visible damage to teeth on gears, all splines, shift forks are in good condition. . We couldn’t get the shifting forks and shift shafts lined up properly , so they will be safely packed on the outside of the transmission. Main is marked M100 Doug Nash Racing Inc, tail 3857584, and cover is marked 3831707. One of the mounting holes on the tail, is damaged (see photos), other that that no cracks, damage or repairs. Shipping quoted is for the lower 48 states only all others in
