Re: Rearend Chevy Corporate ?

If we are talking strictly "truck" axles, there is some confusion in terminology.

The older "removable 3rd member" HO/52 and HO/72 axles are sometimes refered to as 10 bolt or corporate 10 bolt too.
It is true that the factory discription of "bolts" is for the ring gear, but the cover happens to have the same count. That is probably why the HO/52 get called 10 bolt too.

Here is a quick discription of the most commonly seen diffs.
This is not all that there are, it is hardly an exhaustive discription, but in general a decent guide.
