SA trans + FB trans = My trans.

Ok heres the deal, the syncros and fifth gear in my transmission are bad in my SA and I am looking to swap parts from the inside of an FB transmission over to mine, and my question is, what parts are interchangeable from the FB trans to my SA trans? I have heard that the FB also has a taller fifth gear.

All help is appreciated. :)

Nevermind, did a search and found the info I needed, I have the later model SA and if I understood correctly then I can just swap the tailshaft housing. Correct?

yeah depends on the vin #, but the later ones can swap tailhousings.

Ok I looked and I have the earlier model SA, What do i need to do to swap it now?

I have removed the insides of the FB transmission I bought.
