Paul, I had conversation with Larry this morning to get my facts straight. The attached pix from Colvin's By The Numbers, the bottom line of page 329 lists one M22 with 4.56/4.88 one pass car. That is Larry's car. Note that the top page has penciled in "post model". He distinctly remembers M22 being listed on the window sticker.

Larry ordered the car in Feb after the L78 was released on Feb 15th. The M22 was released late April, Larry's car was delivered in June. Assumption is the delay was waiting for the trans. Unfortunately the trans is now MIA.

Larry broke the cluster gear very early on. He took it to John D, lead heavy repair tech at Schukei Chevrolet and go-to guy for hi-po car repairs
John calls Larry, his dummy shaft to retain cluster needle bearings for assembly was not large enough (7/8"). Larry, a tool maker by trade made him a 1" dia. dummy shaft.
The 1" cluster shaft was not released for M20 and M21 until the '66 Model year.

Al Colvin and Warren Leunig have been involved in documenting Larry's car.

Any additional information would be appreciated. - Bill W

Yes, I reviewed all the data again and we now have GM records that show there were no production cars with an M22. Now it's possible that the car was ordered through the COPO program and that would be another story. I'll wait for Warren to chime in anyway about this M22 info
