That number is not consistent with any type of CON VIN from a 1971 model GM product. The CON VIN format should be N1Lnnnnnn, where

N = a number designating the GM division of the car (Chevrolet would be 1, and I believe Pontiac is 2)
1 stands for model year 1971
L = a letter designating the vehicle assembly plant
nnnnnn = the last six digits of the sequential VIN of the car

Colvin's book makes no mention of anything regarding the TCS switch provision

The M22 that I had in my deuce had a provision for a TCS plug in. I'll have to look again, but I don't remember seeing it on this one. I agree those numbers I gave really don't appear to be a sequential vin number, but it's the only other stamping in the main case.
A friend of mine is wanting to sell it, but he wanted to be able to tell a prospective buyer what it came out of. I'm not sure were going to find out.

If your going to look at it again??? Get all the casting numbers... And check the tag number, it should start with a 3 not a 9... Crash

Crash, it does have the TSC provision. I missed it the 1st time. The tag reads 978766 WO.Not sure the tag is original to the trans.
9352648 side cover
3978764 GM tail
3925661 case
PIPO3C STAMP
21200268 stamp on other side
Could be a case of mixed pieces.
