8 3/4" from a 1/2 Ton P/U or Van For "A" Body

"I think only the 1/2 ton came with the 8 3/4. The 3/4 ton had the Dana."

I must respectfully disagree. Most 3/4-ton trucks and vans had the Chrysler 9-1/4" diff. Some 3/4-ton trucks may have had the Dana 60; I'm not sure. The 1-ton trucks generally had the Dana 70.

Well whatever, my point was simply that the 3/4 ton did not come with the 8 3/4.

Yes usually the 8.75 was not in 3/4 and 1T, the 9.25 replaced the 8.75 in the 1/2.

1T had 60's for a long time before 70's got under there, D-70's didn't get into and Dodge till 79, and weren't in the normal 1T, there was an option for the 60HD and 70 in the W-350, but most were regular D-60's and the 70's were used in the larger trucks.
