My takeaway from the experts is that a lamp made in the 60s on fresh tooling is generally better than a new lamp made on poor or worn out tooling.
According to that book put to gether for police investigations, Chrysler didn't start using 6014s until '73 IIRC.
I'm sure we can scounge up some period correct lamps if you want.
Like I said, I've got two - their just not matched set.
Early lamps don't have the amount of markings on them latter lamps do.
