I have a 71RR with a 383/727 and I want to convert it to a manual transmission. I want the manual transmission to have overdrive and I am considering an A833 O/D transmission. I have researched it online and it appears that all of the standard 4 speed parts work with the later A833 O/D transmissions. I found an A833 O/D locally for a very good price and I am considering going and getting it but I wanted to check with you guys and make sure I am not missing something about this conversion that will cause me a problem. The pic is the unit that is for sale locally. My car is very far from original so a "correct" conversion is not needed just a functional set up. Thanks!
