Quoted from ForceFlow:If they're unobtainable, I'd scan them.
Personally, I'd put the new plastics on, but also put on plastic protectors to help protect them.
If those aren't available, maybe trace and cut your own. Or, maybe work with someone who does produce protectors.
If all else fails, throw on some plastic washers, especially on the slingshot plastics.
Agree, scan them and plastic protectors.
If you go washers, don’t forget around kenny and chef.
