I have for sale a 1964 GTO Lemans Delco Remy Low Side Horn. This is part number 9000475 and date code is 3H3. This was tested with a battery charger and it made noise but not a good clear tone. So this will need work. Please look at all the pictures. This is used and sold AS IS. Please email with any questions and please check out my other listings. Shipping will be $10.
