1\2ton suburban rear axle

[38chevyhotrod]

I have a c10 suburban with a really bad rear axle, one of the tubes was loose in the housing. I welded it up but i cant get it to stop leaking oil from the spot welds. Also the axle inner components are in really bad shape so i need another one.

These things i know.
It has 5 lugs on a large(5" pattern)
It is a 12 bolt GM with 41-11 gear(3.73)

The only thing i need to know is how wide the axle is, is there somebody who knows this?

I also like to know on what other cars/trucks i can find an axle with these specs. It does not need to have the brackets because i can weld those on there myself.
