10” rear drum - front shoe hold down

Good evening all,

Doing some work on my rear drums.
8 1/4” rear with 10” brakes. Probably from a 75/76 dart. Currently installed in a 65 dart.

I got a hardware kit, new shoes, and new drums. Most of the hardware kit has been installed. I’m having an issue on the front brake shoe, where the hole for the spring is too big to hold the spring. Can I put a washer behind the hole? Looks jenky, but should hold the spring. More concerned about safety/longevity. Pictures of old shoe and new shoe for reference.
