'69 3/4T 2wd Need's New Rear - What Fits?

[LilTruckMan'69]

Truck had d-60 w/ 4.10's and housing and pinion are shot so I'm now sourcing a replacement.

Me and a buddy have a line on a 4x4 (80's?) w/ 4.10's that we could part out w/ each other.

He also has some 3/4 ton rears w/ 3.73's laying around.

I believe I want to stay w/ 4.10's but I'm open for suggestions. (I assume 4.10's best w/ full load and a 350 powerplant) Trucks purpose is to tow a camper, car trailer, and small 4x4 pickup.

My main question is which rears will be the best fit? Width should be ok I assume but what about spring perch size and location between the different years and body styles?

If one of those 3.73 rears has matching perches I think I will roll it under and see how it goes for now since I will not have trailer and/or camper till truck is up to par.

Thanks in advance to all who respond.
