67 dart,, only made one year,,

I think the first year of a new body style was 'different' from the subsequent years because there was a little of the prior body style mixed with 'new' body style stuff, which was improved/changed in later years.

67 a-body, as pointed out, and 62 b-body which parts are grouped as 62-65, but the k frame, gas filler neck, wiper arms, etc, are specific to the 62.
