'69 Turbo 400 code?

[Mrlzybones]

I've got a turbo 400 trans with the code 72-CY- 1732. The tag was striped & painted over however there is still a partial pice of yellow paint near the id tag rivet. The date code is "348". The partial VIN looks to be 12N161400 stamped on the driver's side. The case number is 8623462. From my research this is a 400 with high shift points possibly offered in the high horsepower novas,camaros, chevelles camaros. Any help deciphering would be appreciated.
