I'm looking for a 23 spline A833 for my 1969 Roadrunner. From reading I see the tailshaft housing has different shifter mounting locations. So my question is what year A833 do I need for a direct bolt up ?
There are 3 input diameters.
4.35 small block and pre68 big block
4.87 big block
5.125 overdrive 75-80
Brewer's sells different input collars and I think an adapter ring
The trans mount moved to the automatic position in 70 and you have to use an auto crewmember
You need the long tail shaft b or e body trans. Not the short a and f body.
First gear changed to 2.47 from 2.65 in 71 and 3.09 in the 75up overdrive.
