My dad bought a new 55 ford and i managed to tear 1st gear out of it . Okay i was a teenager and never knew how to drag race , ha ha . But when we removed the trany it had that metal cover on it but the replacement he picked up never . It had the side plate that came off. So luck was with me as he said ," yeah they put a cheap made transmission in it , i think this is a better one" . I still don't know if he knew i was out trying to drag race. So , i believe that might be a 55 ford passenger car transmission.
