Never been mounted. New without packaging. Swap meet find 20+ years ago. 3/8-24 thread. Have been sitting in a drawer ever since. Haven't seen daylight since last week. Cleaned with soap and water. Look really nice. I'm sure a coat of wax would make them perfect.Classic white ball with the standard shift pattern embossed in black.I have no idea what manufacturer made them , nor do I know what brand shifter they fit. Just trying to help a friend get some nice stuff into someones hands who can use it! Thanks guys. I can email pics if someone is interested.
