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

Everyone is saying how rare the 8 4/4" ousings are getting to be.

I live in a very rural area. Nearest medium sized city is 2 hiyrs drive. (Watertown to the west, Plattburg to the east)

Not a lot of old Mopar "B" bodies or the like around, but lots of pickup trucks in barnyards, etc.

I know there are 8 3/4" diffs used in those trucks. I had a '78 that had one.

Are they harder to narrow than units from a car?

Will standard "A" body axles work in those housings.

What about brake components?

Seems like the pumpkins would probably be the big pinion.
