Have you accused your wife of moving them or throwing them out yet?
The only other way which I can locate lost parts is to buy new ones. The lost ones appear out of nowhere within days of receiving the new ones.
These springs are not high tech items. They don't do anything special. Take the one you have and go to some hardware stores. Heck, an oldtimey screen door spring could be cut to length and work for that job.
