Same on GMC. They are referred to as Corporate rears or non-Dana in GM parts books. That is the tallest gear you can have with these rears.

Re: what axle do I have? 1970 C30
That's it alright. And you have 7/16" studs with flat back lug nuts like castle nuts. When the trucks got disc brakes in '71 the studs went to 9/16" and spreader rings with tapered holes were utilized to accept chamfered lug nuts
