I've always wondered how to identify the rear. My cab has the warning sticker for the limited slip differential. It also leave 2 patches on my smooth concrete driveway when I spin em

According to my shop manual, I have an Eaton 3:90 as it was the posi available that year for a 1/2 ton. How would I know for sure? It has a 10 bolt cover. That's all I can see. Are there numbers somewhere? This is a part of the truck I just haven't messed with yet.
