I've wondered about these snap-in caps from McMaster-Carr for years, so I finally bought a box of them. They work great and look nice -- the pics below really don't do them justice. They differ from the originals as follows: The finish is matte nickel-plated steel instead of chrome. Great candidates for paint. They sit pretty much flush -- the originals sit about 3/16" proud. $6 shipped with tracking. Make PayPal payment "To A Friend" to: email@example.com and be sure to PM me your address.
