I have seen the partial VIN in 2 locations;

1..on the top side of the pan frame rail, driver's side above shift lever.

2..on the passenger side of the bell housing near the top

most have been in the frame rail location....you will need to have tranny out of the car or have a good mirror/lite to see either location.

**this tranny was only available in the L78 Nova/Chevelle and the LT1 Deuce and Z28. There is typically a pink CW ink stamp on the trans. case.
