Can anyone provide a part number for a 65 Valiant gas cap?

OK, I found some stats on my working gas cap I modified to fit. Its a Stant chrome with a straight bar, and the 'plug' is 1.350" and the tangs are ground to 1.511". Fits like a glove but wouldnt fit if I didnt grind the tangs down. I dont know what part number it is and the link is not working yet.
