I picked it up a short time ago and just got back home. Its a short tail PW-69-#### th400, (still has the tag), and the guy said it came out of a 69 GP, just removed a few days ago. He was parting it out.
I got the trans and stock converter for $150. Its grimey, as is to be expected from a trans that was just in service, but splines, seals, casing, etc, all look good.
It now goes in storage...just like the rest of my parts...till I can work on it again...
