Greg the one you posted is too red IMO and I think my recently restored '68 road runner finish panel is just a little too red also (attached). I have a photo of this one which is the original from my car and restored and two other un-restored originals finish panels and you can see the originals are less red and more maroon. I wish mine was more maroon so that it was closer to the color of the tail lights. I think the original intent of the color was to make it appear to be a continuation of the tail lights so IMO it should be a darker red or maroon color.
