1961 Commercial Chassis Rear Brakes

[Gothzilla]

I am having a devil of a time finding springs kit for my '61 Hearse. Any help locating these would be appreciated.
Thanx,

Springs or brakes? 
Believe Eaton Springs were the original supplier for your car's springs.  Have you tried contacting them?

Being a somewhat rare commercial chassis, the fact you are having difficulty goes right along with comm. chassis.

Springs for the drum brakes. These seem to fall in a hole between years that are available easily. Unless they actually are the same and the kits don't acknowledge CC.

     Ahhh, springs for your drum brakes!  That one went right over my head, sorry about that.  Good luck in your search.
