Good day to all, I am restoring a 1968 GTO and am stumped. I have been on other sites asked for help with this issue with no avail. Could someone that is familiar with a 1968 GTO with the endura bumper please tell me the correct mounting placement for the high and low side horns. I can only find Camaro and Firebird images and it doesn't seem to be a huge issue but the devil is in the details. Any and all help or images would be greatly appreciated.
