1969 Dodge Charger
2-door Sports Hardtop,
383-4v
84,017th car scheduled for production at the Hamtramck, assembly plant.


PP = new process
833 = trans type
2020 = assembled Tuesday, February 7, 1967
0277 = 277 built to yours on that day


so this trans is a hodge podge? verify the 2020. A 67 case should not have a vin pad. maybe it is 2820? 2820 is Thursday, April 17, 1969
