[HEMIDARTDAVE]

If the photographer or author incorrectly labeled the silver Dart as running SS/B, possibly the "Manhatten Speed Parts" name was wrong also, since Manhatten Speed Shop claims it never ran a Hemi Dart. If it was a hectic day, and there was no lettering on the car, that might happen.That souvenier program, as Mark said, or some list of the Darts that competed that day might help clear things up.
