Rear end casting date 4/25/27


Recommended Posts

I have a rear end that came with a chevy i bought...none of the numbers jive with chevy parts books.  Perhaps it is a pontiac.  It has a torque tube. Did early oakland/pontiacs also use a torque tube?  If not then I'm on the wrong forum to get me started...TBlack

Pontiacs had torque tube setups from their start in 1926 through 1928.  They went to Hotchkiss drive in 1929 with the Series 6-29 cars.  


The early torque tube carrier and torque tube was part number 342495 for '26-'28

There was one with a different gear ration than standard in 1928 that had part number 526562


Those numbers should be stamped someplace on the casting, I believe.


Hope this helps.  As Mr. Kornkurt says, photos might be helpful.
