It was originally a M20 from a 1969 Chevy (Chevelle?)
The input shaft appears to be changed, with the groove should be a M21 input shaft? (internals probably changed out) 19A339024 - VIN of car it came from, the A is the plant the car came from also. P9C10A - Mar 10, 1969 M20

Looks like a M20 case (A) at the end of the date code, with M21 input shaft. So its a M21, as it must have a M21 Cluster gear also. M20 has 2 grooves, M21, 1 groove. Far as I know!
