There should be a stamped tag on each diff, usually rear passenger side. They are usually in a format of S#,## ##### where the S = Slip (LSD) and the next 3 numbers are the ratio.

no (S) and the only numbers on it are 1 210 411 and there stamped into the case of the rear end.

There is always a chance the tag is missing. It's usually a stamped tag attached to one of the cover bolts near the right axle stub.

I looked there as well and no S but figure this one out the number on the cover was 1 210 433 so I don 't know ghead
