I have a new unused horn button for a 66 GT350 factory deluxe wheel for sale . It has been on my shelf for a long time as the date on the back of the package indicates. This horn button was made by California Pony Car but has been out of production for many years now. No one currently makes a replacement which makes it tough for those restoring a 66 GT350. It is identical to the factory cap in all aspects once installed. I kept this for the possibility of needing it for a car in the future but that hasn't happened so I am going to take a chance that I will not need it and go on and sell it. 500.00 plus 20.00 shipping to US address only. PM me with any questions. Thank you for looking.
