Pickup Selector for 1982 Thunder 1-A Guitar

I'm new around here but I've owned my Westone since May 31, 1982. It's about to become my "daily driver" again and everything works great after not being played for at about 20 years EXCEPT the pickup selector. It won't stay in any position other than the middle position. Did I see somewhere on here that someone is making replacement parts for Westone guitars and basses? (I would post a pictures but I'm not sure how and servimg.com doesn't seem to have a registration option." Any help or info on how to get that selector replaced, and soon, would be most appreciated.

Hello TJ and welcome.
If you're a stickler for originality, one of the members may have a spare part available. Otherwise a standard 3 position toggle will work just fine.
