I got a useable steering wheel just like my original, even in the same color. Along with a new horn button. I have the original wheel, and ornament. Mine is two spoke with the half circle horn ring. In the 65 parts catalog it shows 3 pieces I'm missing and I'm wondering what they're for and if it's ok to use without them. One of them is a steering wheel spacer part #2401209, the other is a steering wheel ornament retainer o-ring part #6023346, also there is a felt silencer that says is not serviced. Are these still available? What will it do if I don't have them anymore?
