I would say during 1965 model year. Have a June 65 produced Dart 270 wagon with the Certicard loose in glove compartment. Adding the black plastic holder was 1966.
Anyone have any pictures from Universal Dodge in Palo Alto, Wegge Motors in Pasadena, Valley Dodge at Van Nuys and finally Earnhart Dodge in Hemet CA? Any hrp is appriciated.
I would say it's the last week. Friday 26th was the last production date. Following week they changed tooling and stuff and the 1975 production started August 5th.
Looks great. I make a copy of mine tomorrow. I talked with Marcin Detroit today. He had no input. He referred to Dave Wist at mmcdetroit.com. I will call him tonight.
Has the card had same dimensions over the years? I can pm you a copy from 1965. I have a friend in Detroit who used to work at Highland Park. I will ask him.
