904 727 parts interchange

The front band lever and the pivot pin are the same as are all the bolts except the 727 uses 7 pump bolts and the 904 has only 6. Valve bodies are interchangeble if the middle bolt at the rear has an elongated slot instead of just a hole. I'm unsure of the park rod but the actual pawl and the guide are the same. The springs and rollers for the over running clutch are probably the same as well but the races and number of rollers are different.
