Has anyone ever noticed a difference in the coloring of the 69-70 MACH 1 Dash Emblems? I am seeing Black Border and Lettering and a Goldish colored Border and Lettering? The Gold coloring does not really look like it was black and faded to gold. I'm just wondering if it is an Early vs. Late thing? or Factory vs. NOS thing? or if it is really just black fading to a gold color?
