I have 1 ton and 2 ton AD trucks and best I can tell those hangers are the same, also same as 3/4,ton, and 1.5,ton.
One on my 1 ton is worn, I have salvaged one from a 2 to. But yet to replace it.
Should also be same part at all 4 corners of the rear springs, so lots of those hangers out there for the picking.
Hope that helps.
