Any 833 4 speeds to avoid?

I don't believe A-833s (conventional 4 speeds) were used in pickups, but OVERDRIVE units were.

But some guys put A-833s IN pickps

There was no "granny" A833, 3.0x was the lowest gear.

But if you want something for an A body, you don't want a long shaft, and generally, stay away from the earlier flange drive 4 speeds
