Pin, Cam Cover Filter Retainer, for 90~95 ZR-1, LT5. Sold individually. two are required per engine.  Friends, there is nothing special about this.  Plain ol' bailing wire is what it looks like and works just fine.  I was amazed to find them in a GM pkg with a PN, so we listed it for giggles & to let you know the reality of this part.

NOTE: This is a NEW, GM OEM part.
