Re: 63 Muncie M20 Transmission Pat Pend
Larry, I have no idea what those numbers are. But I do know that a Nov '63 T-10 was never installed in a new Chevy. They were switched to Muncies during April '63. BOP and Studebaker may have used them later into '63 and '64 production? The spline on the main shaft and the gear tooth counts could provide clues.
