A guy in the northeast had a pair of these for sale on this board recently. It ws a long post. I want to say Welch was his name. Sorry I can't help more, I'm looking for a pair for my 67 CJ-5(cone shaped amber plastic).
Try quadratec, I think I've seen one in their catolog but I'm at college and the catolog is at home. They don't show it on their website (quadratec.com) but I think you can request a free catolog from them and that it is in there. Good luck,
