As BlackoutSteve indicates, the standard horn placement (non RS, non low note option) is shown on UPC 12, A8. UPC U3, A1 shows horn Placement for the RS option, and the low note option. If your Camaro has the basic 2 horn setup use A8. If horns are still intact with their original mounting brackets, they will only fit one way (because of the mounting tabs) into the headlamp housing and radiator support.
