My guess is that it should work, any ideas?

GM 8.5 inch 10 bolt 3 series posi. Accepts 28 spline c-clip axles. It is from a 1987 K10. This is the Eaton Automatic Locking Differential GM used in Trucks and Vans.
 
Where are you going to buy this from?

is a piece of sh.. its a whizzz bang style, one tire will spin then lock the other. they are not the best, but work, i hated it in my V8 S-10

this is not a piece of sh.. its actually a posi. Notice the S spring :)

Let me know what you think, i am curious myself and yes the carrier i am referencing is the link you posted.
 
http://www.gearsareus.com/ I got my Eaton here. They were very helpful. The install kit was great too. They might be able to tell you if the unit you are looking at will fit.
