    I need a new ring pin and differential in my 79 gmc pick up and I know of a couple of blazers and a suberban that I migh swap with. The suberban has a dana 44 from looking at the cover. as long as the ratio is the same I am thinking of using it. I think the blazers have corp 10 bolt front axles.
    Are the diferentials/and or ring and pin interchangable between dana 44 and corp 10?

    If you want to exchange the entire housing then yes, they are interchangable.

    But the Ring & Pinions are NOT interchangable between 10 bolts and d44's.

    Suburbans and Blazers have the same running gear in 1/2ton applications. 3/4 ton Suburbans are different.

    it wasnt the model of the truck that made it have either a 44 or a 10 bolt front it has more to do with year and drivetrain ordered/installed, in 77-79 years either 10 bolt or 44 could have been installed depending on year and drivetrain ordered, this goes for all trucks up to 1 ton
