Hy Matthew Blair, more research, Wagner numbers 36441 for 15" X 4", 36440 for 15" X 5" rear brakes, if you could give me spring lengths I may be able to find them, Euclid lists a spring set for manually adjusted Wagner brakes p/n E-4027, contains 4 spring 4 1/4" long. and 4 springs 6 5/8" long, replaces Wagner F98318, but I think this set is too new, hope that helps.
