Then on the right side there's a white sticker that is just a little more towards center of the spot where the rear leaf springs bolt to the bottom of the axel's right side. On mine, this white sticker faces towards the front.
Both should say somewhere on them either "3.55" or "3.92".
I know I actually wondered if I truly got the 3.92 with the limited slip until I got under my D and saw right there on the axel that is said "3.92"!
