The Ford Barn

Picked up this flathead overdrive unit that appears to mount somehow in a Ford torque tube.
Has 6 spline in and out, operated by single lever.
Has no casting marks, or maker marks other than on the UJ.
Anyone ID it?

Its about 33" long

Asked on the HAMB, some people think its for an AA Truck??
Thanks
David

Looks like a dual-high aux trans for a 28-29 "AA"truck.It is direct & underdrive.

Yup. Definitely NOT an overdrive.
