66 A body vs 67 A body bucket seats

2 or 3 years ago i stopped in at the Legendary vendor spot st the Nationals dor some info on this very question. According to one of the salesmen at Legendary, the seat bottom and back frames are the same for 66/67 A bodies and 66/67 Chargers. I can’t remember if he sa!mid other 66/67 B bodies used the same frames or not. He said the backs were the same as well. Did not discuss side covers or the slides
