As far as I know the not even the wheels interchange.
I thought the 1962 Dart was a "B-Body"

The three-tier model line-up was retained, but the Dart Seneca was replaced by the Dart, the Dart Pioneer was replaced by the Dart 330, and the Dart Phoenix was replaced by the Dart 440. Over 100,000 Darts were sold in 1962, using similar engines to the larger 1960-1961 models.
Though the Dart got smaller and lighter, it offered powerful 413 cubic inch V8 engines (except in the wagons), with availability starting early in 1962.
