The Ford Barn - Brake Springs

I'm looking for some brake return springs for a 1938 one ton with manual brakes. I need some help with additional sources. I found some at Job Lots but other sources have come up empty. I still need pairs of the following springs: 81T 2036B (rear, orange, 4 1/4"), 81T 2296 (front, red, 3"), 78 2297B (front, orange, 4 5/8") and a couple of springs I haven't been able to find numbers for in the Green Bible: front green 4 1/2" and rear black 5 5/8". I'm also looking for the front and rear return springs for the operating levers for which I have not yet found any numbers in the Green Bible. I would appreciate any suggestions.
