Just for the record, back in the 80's when Downer was THE guy with the NOS parts, I traded for a pair of NOS Challenger park lite assemblies for a Challenger I was doing.
He had no less than 10 NOS pair on hand at any given time, with correct 70-71 pigtail. There were as many boxed with the gold colored finish as there were with the bare finish.
We went throught them all to make sure I got a pair that matched, and again all were NOS in the boxes.
