seat track knobs

[68r/t]

 My 68 is missing one of the seat track  knobs that go on the lever and the other one is black plastic.
I have searched the forum but can not find anything that Say's that they are black plastic or chromed.
Can someone please verify what they look like and maybe with a picture, it would be very much appreciated.

thanks

The knob for the seat track is black plastic and the knobs for the seat back are chrome.
