Diff swap

I'm looking at swapping a one ton rear diff into my 96 f250. I'm wondering if my drive shaft will be the right length or will I need to shorten it. Reason I swapping diffs to have 4.10 gears

You can either swap the ring gears and pinion, or the entire axle. If you just swap the gears you shouldn't need to change your driveshaft length. If you have 4x4 you need to make sure the gears match.

rears from the srw 250 and 350 trucks are the same, all sterling 10.25 axles, though there are some slight variations between the earlier 86ish-91 ish and later 92 ish - 97ish axles

If your rear is from a 93 it's still a sterling 10.25

Exactly, but you could just swap carriers and be done, no heavy axle to move

swapping carriers to me is a bigger PITA than swapping axles, because you will have to set up the gear correctly and replace bearings and things and do it twice whereas swapping axles should be much quicker, at least for me

I agree. They are already set up the way the are, I wouldn't mess with them. Swap the entire axle if you got one.
