    I have a 350/203 combo, and a 205t/c that had a 350 on it. What do I need to do to mate the 350 from the 203 to the 205? I do still have the adapter from the 205/350 combo.

    Also, they may mount different depending on year. My '73 NP203 uses Spicer yokes, while the '80s NP205 uses a Saginaw flange for the front & a slip yoke rear.
