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?
