Starter Plungers Parts ???

I'm starting to rebuild my carburetors on my 77' KZ1000A. The stater plungers aren't in to bad a shape but the plastic collars are nearly gone as with the rubber dust caps. I see that you can buy the rubber caps still but the collars appear to be obsolete?

I saw somewhere that someone had some collars made out of aluminum which to me was a perfect idea instead of the nylon. Does anyone know where you can purchase these collars whether nylon or aluminum???

Also, Is there any members that have a decent set of plungers they be willing to part with?

Talked to Mike Ames at Z1 Ent. today. Set me up with the right parts to order.

Does Z1Ent have the plastic starter plunger collars? (16073-014). Thanks.

Edit: never mind --- found it. Z1Enterprises.com --- Choke Rod Collar Pull Nylon - ZSM073-014
