Pardon for the dumb question, but if you are not sure what model it is, how do you know it is an overdrive unit? I have a spicer 4 spd aux and they made a few different versions so I had to make sure my model was an OD because they offered straight drive and underdrives for them. It would have no use to me if it was not OD.

Just asking as I have never seen one like you have here.

Was this to go in a torque tube app or is that a slip yoke setup on the rear?
