I would suggest you keep an eye on ebay for a replacement and also consider making your own spring. MY 41 is especially difficult to MAKE the hood open with a broken release cable or other latch impairment. You just cannot reach any part of the hood latch mechanism through the grill and must remove a front tire, an inner fender, and reach blindly up to the hood lock plate with a long screwdriver to pry at the spring lock lever. With a lot of patience and luck the lock lever can be pried open releasing the hood.
I made my own
1941 safety latch spring release when my spring broke, another common occurrence from rust and years of usage. I used a spring I got at Ace's Hardware, some washers, a nut and bolt, and a cotter pin. See attached 1st five pictures.
Has anyone tried this truck latch spring on ebay?
Truck springHere is how I modified my hood release cable so in an emergency I can open my hood. It consists of a wire running down from where the hood release cable attaches to the hood lock plate, a block of wood on the end of the cable, and everything tucked behind the baffle at the bottom of the radiator. More pictures attached.
Good luck, Mike
