plastic discs on LS1 injectors

I have a set of LS1 injectors I plan on using in a 5.3 swap. The plastic discs at the injector tips on 2 of the injectors are partially missing. Should I run them as is?.....replace the discs?......or should i just look for a used set of injectors?

I don't have a picture of my injectors, I'm refering to the orange disc at the end of the injector in the link below. One of the injectors is missing roughly 25% of the diameter of the injector. Another has a 1 mm notch out of the disc. And 2 of them have cracks.

Can these discs be replaced? Are the discs a common size?....maybe something I could find on a FWD GM car in the salvage yard.

PM Chuck Leeper (Old Geezer), he rebuilds injectors for a great price.

Did they work?

I have one leaking and the plastic disc is cracked enough I can separate it with my fingernail and get it completely off the injector
