Now that you have a sheet of brand new material, you can put two more spares together! I'm assuming those two are the whole crimped assemblies and not just the 1/16" plunger pins.
After 30 years of use, I sometimes find those midget pin assemblies loose in the diaphragm. I'll bet they just pulled them on out of the worn material, and then saved them for future rebuilds...
Cory rocks, I just made a half dozen for the big brother 3400-4000 series. Something inside to do while waiting for the ice storm glazing to melt off the roads.
