I received my list of potential LCP's in my -14A fuselage the other day. I have one of the "potential LCP" red parts on my shelf still (idler arm). It is still wrapped in blue vinyl so is clearly punched. I can document this with a photograph. However, a couple other potential red LCP's have already been incorporated into my build. I am 100% certain that they were punched, but have no way to prove this as I did not take photos of the parts prior to working on them. My question going forward is how does one prove that their build does not contain LCP's? I am not going to risk damage to my build to replace these good parts with other good parts just for the sake of documenting the new parts.
