1950's Borg Warner overdrive from the back of a transmission transplanted into a torque tube. Flange indicates that it is most likely Model A, possibly 1932 Ford. Total length of the 2 pieces would tell which.
The general type of the overdrive was used by nearly all US car makers at one time or another.

I've been researching OD's and stumbled across the add. To bad something like the Ruckstell isn't still available. Looks like the Mitchell is probably my best option. Still a lot of work to install.

I've had both.
You can't go wrong with the Mitchell.
