Ed, I see a bunch on E-bay, $48.95 up to $300 on NOS. The later version, '78-'81 Camaro were the same design, but had a twine like wrap molded on them. (those black ones are the stickies like I mentioned to 27cheyguy).
Just texted Shane, he thinks he might have one. Going to check when he gets back from Dodge and let me know.
