Transmission, drive shaft and differential question

A-230 3 speed with synchro in all forward gears, will need same bellhousing the A833 4speed trans uses.
Your 3-speed trans has a output flange with 4 bolts for ball and trunnion front joint driveline. You can find a 4 speed A833 with the same output flange, only made in 1964-65

You can upgrade to a front slip yoke for the A-230 and A833 trans or A833OD It looks like a A833 but has overdrive instead of 4th gear. If you use this OD trans, you will need a different bellhousing with a larger opening due to the larger front input bearing needed on this trans.
