SS rear

[kenw]

Hi everyone. I have a rear out of a 1986 Monte Carlo SS with an axle code 9TZ C085 2. I can't find this code anywhere. Anyone know what it is? Thanks.

 

[-83MONTESS-]

If it's stock it is a 7.625" with 3.73 gearing. The 83-84 had 7.5's with 3.42's because they came with TH350's. The 85-88's got the 200-4R with the 7.625" and 3.73s. Posi was an option on all of them.
