For you differential guys:
When I had my old Z71 I found a good deal on a front and rear ring & pinion set. But they weren't made for IFS so I just left them laying around. Now I am wondering if the rear one will fit my 2003 Silverado's 8.6" rear end. I have been looking online and they all say 8.5" and 8.6" like they are interchangeable. If they are interchangeable, how will I know what differential they were made for and will it hurt that they have gotten rusty from sitting?

Some say the 8.5" and 8.625" are the same but I still disagree. 8.5" has left hand ring gear bolt threads.
How do I find out what I have?

It's an 8.625" if the 2003 has the stock axle.
I mean how do I know what this other set here is? This is what I know about it:
It is a 4.10 set
There are 12 bolt holes
The 12 holes are right hand thread
(I think) they are some GM set.

They're from a 12-bolt if they have 12 ring gear bolts holes.
