I own a 73 Corvette last month I ordered right and left grills from Ecklers, Corvette Central and Street Edge and none of them fit. The originals are about 14 1/2 inches across at the widest part, but the 3 sets I ordered were about 16 1/2 at the widest part ! ! ! Does anyone know where I can find the proper dimensions of the grills for a 73 ? Help Popeye Help.....
