Early Muncie Decode

Hello,

My Muncie 4spd on my (in transit) 69 BB Camaro has the code P9P17. From what I have read the early 69 Muncie's did not have an A,B, or C after the code. The A,B,C are what designates if they are a M20, M21, or M22. So with that said, how can I can tell if its an M20 or M21?
I am ruling out M22 because of no drain plug of course.

Thanks for the help!

Anthony
