I posted a message on Feb 3rd about my 67 rs convertible w/ac being a possible L30/m20, but at the time was unable to get the trans date code. Also, the shop that restored the trans spoke of the vin being stamped on the trans, which matched the cars vin.
We just got done pulling the trans to fix a leak, and I'm excited to report that the date stamp ( R 7S02 ) and the partial vin ( 7N132678 ) both match correctly and completes the last piece of the puzzel.
My question is, how rare is it to have the partial vin stamped on the early models of the m20 trans? My understandiing is that we didn't see this done except for the Z-28 and SS in 67.
Here are photo's of trans http://i268.photobucket.com/albums/jj18/34gogo/Picture011.jpg
