3 speed tranny question

The floor shift car is an A230
The 66 has either an A903 or 748. Neither of those transmissions has any provision for a floor shift.
The good news is, your A230 will plug right into the older Bell Housing and take the same trans mount and drive shaft as the 66

Good news is that it did bolt right on my 66 bell housing and the 66 linkage rods are a bit to short. Just going to extend them out a bit and a little bending and adjustment column shift should work perfect Thanks whitepunkonnitro
