Check out www.DemandAAM.com.  There are the OE supplier for your 12-bolt axle.  You have a 9.5" Salisbury axle.

 

You'll love the truck even more with those gears.

19-current have two axle suppliers.  OP will have to verify by VIN if its AAM or GM axles.

Who supplies which one?

 

AAM purchased the GM Saginaw Division for axles some time ago.  GM opened up a new factory?
