Phillip: I Do not believe that it would be very possible or economical to exchange Tailshafts......................................
Trans output shaft are different in length and diameter as I recall andmaking
a output shaft would be a small fortune. Both tail shaft have rear mount in same place and take same transmission cross member . The yolk is twice
the size on front of drive shaft on 727 than on 904. Nevertheless , it would
much easier to make a new drive shaft or rework a stock one than modify
the transmission!
I am sure that there are some transmission builders than can give you
better advise than I can.................I have not rebuilt my transmission since
the 80's. More effective to just cut a check to Pro Trans and cheaper
in the long run with my skills.
Phillip: Will answer your E mail tomorrow.
