66 formula s stripe color

I want to put the stripe back on my 66 formula s. The car is dark green and has paint code 999. I do not know how to tell what color the stripe was as it has been repainted. Would like to put a gold stripe on it. The interior is black. My questions are, with the black interior could you get a gold stripe? and, I do want the stripe to be correct, how do I match the paint color for the stripe? Any thoughts are appreciated.
