Can anyone tell me what the numbers represent.
I know the PS code is a 10 bolt posi. With 3.31 gears. I think it is out of a 69 Camaro. Don't know for sure.

I am not an expert by any means but from the Camaros. org site that stamping does not seem to be from a 67-69 camaro. A "PS" from a 67-69 camaro should be a 12 bolt.

Again I am not an expert so I would suggest checking camaros.org for more details.


67-69 Camaro Axle Code Format

Axle Code Format: aa mmdd fs
p

where:
aa = application code - two alphabetic characters
mm = two-digit numeric month (01-12)
dd = two-digit numeric day of month (01-31)
f = factory plant code
G - Detroit Gear & Axle plant
s = shift code (1 or 2)

p = a positraction manufacturer code, when applicable,
is added on a second line. The posi manufacturer
codes are D for Dana, E for Eaton, and W for
Warner.

Example: BL 1122 G2
For a 68 or 69 model, this is interpreted as a
3.07:1 axle ratio, non-posi, 12-bolt rear
axle assembled on November 22, 67 or 68 by the
Detroit Gear & Axle plant, second shift.
