Please help me decode my rear end.

[afast93stang]

I have the Mustang Catalog of ID Numbers book and it has some codes for the rear end but it doesn't give all the information.

The tag reads

WCZ-V1
2 79 7CA 930

I know its an 8in with 2.79 gears. 7 is for 1967 but im not sure what the CA (date) and 930 (plant code) decode to.


Thanks in advance!

Trevor

7 = 1967
C = month of year (March)
A = week of month (first week)

Don't know about the plant code
