You could make one out of 1/32" thick spring steel purchased at one of the suppliers. Easily bent into shape as rec'd and if it's a "V" shaped spring, the bottom of the "V" should have a 1/32" radius.
I heat the spring w/ a MappGas torch to red/slightly orange color and quench in motor oil. All surfaces are then polished and the spring is tempered by laying surfaces on a 1/4" thick steel plate heated from below until a blue/gray color is achieved. A quick dunk in the motor oil after each surface attains the blue/gray color ensures the proper hardness. The "V" is rolled on the plate to ensure it also has the blue/gray color...this is critical because it's a stress area. If the spring has a loop for a screw, this area is carefully hit w/ the torch and can be a little less hard that the rest of the spring....make sure the heat doesn't affect the rest of the spring by having a heat sink.
Have made many springs following the above procedure and w/ the purchased spring steel. If 1/32" is too thick, it can be filed down, but must be repolished to avoid breakage....file scratches cause breakage.
The easy way would be to buy the spring.....Fred
