Help with rear end swaps

[harrdawg54]

I found some dana 60 rear ends that I can pick up pretty cheap but don't know which one, if any will fit. The first came out of an International pickup that measures 67 1/2" mounting plate to mounting plate and it has 3.73 gears (I currently have 4.10). The second is from a ford (Yeah, I know) and big tube d60 its 65" mounting plate to mounting plate and it has 4.10 gears.The second comes from a ford (Yeah, I know) is a big tube d60 and measures 65" mounting plate to mounting plate and it has 4.10 gears. I have no idea what will fit and I cannot measure my current rear end because it is at my in laws place. Any help would be great. Thanks.

P.S. > I have a GM corp. 10bolt front end that has 3.73 gears that I could swap in if the International rear works.
