You guys have already ID'd this trans fairly well, so not much more I can add.

Just for a quick reference though, my old Oct of 1968 '69Z had it's factory installed M22 without the "C" stamp. The trans was built right before they started stamping those designations.

My VIN was built shortly after the one being discussed: N515415. I'm posting a pic of the trany stamps for comparison. I'm sure others have closer built numbers to compare, but this is what I had to share.

What would have been beneficial on the Ebay trans is if it still had a 3950318 M22 metal ID tag attached to the side cover. No extra value really, mostly just a bonus part.

To me, unless I owned the matching number car, this would just be another Muncie that could be installed and used as desired. No way to prove it's a factory M22, so it really doesn't matter if it was or wasn't. If it has the M22 gears in it, then just enjoy the 1st gear whine and the bragging rights of having a M22 in your car.
