Can anyone identify these light bars?

My buddy has a 36 CHevy pick up and is trying to get a new set of light bars, he picked up a set off ebay i believe for a 36 Chevy but the angles are completely different from what he had. This is what is on the truck now.

 

1934 Chevy used that style. Probably other GM makes of the same period. Of course the actual bracket will change slightly from year to year and from passenger car to truck based on the curve of the sheet metal.
