$68 shipped via usps Priority Mail. R-4S compound, Porterfield part # AP 389. Brand New. Have the new burnishing material present on friction surface and there are no fingerprints or grease/oil on them. I had a Starion but never got around to installing these. It seems I can't get the photos small enough to upload here so I'm going to place an ad on CL Seattle too, and it will have the photos.
