Go get an eyeglass kit. Find a screw that will fit or one that can be modded to fit. Then grind and polish the slot and shape the head to match. Epoxy. For the spacers use some spring bar tubes? Sorry you had an issue with it, hopefully it will be an easy fix. Good luck buddy.
I'm sure it does.
You could just buy an extra clasp and use the part of of it?
