I am currently picking apart an 88 d150 long bed at a junk yard and saw the 10 bolt diff in the back, I want to make sure it's a dana 60 before I purchase it, it has no stamped 60 or numbers on the tube. But it is 10 bolts and has sheet metal tag on one of the bolts that says 41-10 and 4.1 under it. It's 8 lugs and the hub sticks out. Can anyone confirm that is is a dana 60 rear end?

 

Dana 60 has a distinctive cover witch is also used by the dana 70.

 

Agreed, sounds like a dana 60 or 70. It's easy to pick them apart side by side, but harder when you only have 1 in front of you. The 60 usually has 3" tubes and the 70 has 3.5". 60 drums are shallower and the hubs usually have flutes/channels around the circumference rather than a smooth.

 

D150? 10 bolts? Doubt it's a Dana, they didn't run them in the 1/2 tons.
but the corporate 8-1/4 (same rear, but they called it an 8-3/8 model some years if under a truck vs a passenger car) also has 10 bolts.
I suppose someone could have cobbled something in there over the years. How many lugs?
Does it have the axles that bolt on or c clip style?
