4sp Case #'s

Trying to figure out what specifically this is...

Case itself has 8x15x67 on the top
then E 3
and C 97622

The Pad stamp is:
8A138232 (lynch Rd car)
PP 833 2239 0027

Tail shaft housing
C-00539
SS 2

Shift link cover
C- 95664 Z
5x8
4


Didn't count, but looked like a 18 spline unit

Has to be a 1968 B-body, you can rule Chargers out since it is from Lynch Road.

2239 - assembly date, Sept. 14, 1967 (1968 model year)

0027 - 27th unit assembled on that date.
