Hy Pa Farmer, I found a one ton diff. and managed to get one drum off to take spring measurements. After crossing part numbers from United to Raybestos [because Raybestos does not list the lengths of their springs in my catalog], I came up with
Raybestos p/n H140, axle set, brake shoe return spring $5.90 at Rock Auto
Raybestos p/n H407, axle set, adjusting screw spring $4.84 at Rock Auto, hope that helps, if you need anything more, just ask.
