Voltage Regulator and Horn Relay Location on 1963 non-AC Car

[Rob M.]

Is there any information on the exact location for drilling holes for the voltage regulator and horn relay on a 1963 non air conditioned car? From the assembly manual and pictures that I have seen, they apparently go on the upper portion of the radiator support on the passenger side, but I have not found, in my research, any measurements or landmarks to to use for exact placement. There are dimples on the new Coffman radiator support I purchased but the spacing doesn't seem to match the components. Finally, I can't use my old radiator support as a guide because it is a 1966 support. Thanks!

Robert -

The screw holes for the voltage regulator and horn relay were die-pierced at Chevrolet-Indianapolis, who manufactured the radiator support (none were drilled at assembly at St. Louis); for exact hole locations, you'll need to transfer the dimensions from an original 1963 support.

Here is a pic showing the correct locations. There are probably enough landmarks to get you close...
