I have a 55 chevy, I went to a junk yard in iowa with lots of older cars and trucks. I made card board templates of the curves of the rear fenders to guide me. I found 2 41 buick eight tail lights that worked great. I built the edge of the top of the fender out to meet the conture of the lights and also a cover box for inside the fender to keep all try. My first thought was to french in something but this looks so much better and I have not seen it done before. the line of the 41 lights follows the exact conture of the cab by the gas cap. good luck.
