I'm in a pinch to identify a Spicer auxillary transmission that I have.  It has had the tags removed (except for a lone tag on a Chelsea PTO that is already mounted).  The aux. trans. has a casting date of 1970.  I believe, based on information from the seller and a support bracket that shipped with it, it was previously mounted to a B-model Mack.  Please let me know if you might be able to help properly identify the model.

I AM headed to a Mack dealer in the morning (6/21) to see if they can help.
