More clarification! The Ford F150 OD transmission is - to Ford _ a 3 speed with OD. It is a Tremec RTS. The FORD Four Speed is a separate animal, has a cast iron case and not a good candidate for OD in a Model A. The Four Speed Tremec RTS, the one with an aluminum case and fourth gear is 1:1 is most lickely out of a Jeep. Same tranny, same case just different gears on the inside. A lot of the partts are interchangable.

I have been building these kits for a Model A fifteen years now and any part or trans kit that I build is one I would not hesitate to put in my own car. I dont build no junk yard stuff, thank you. ken
