1964 H/SA "ManHunt" Dart driven by Karen Schultz

i don't think we will know. His email to me only said he dropped out of the D/Dart program mid season and did not follow the D/Darts after that.
The photo you refer shows what looks like H/SO on the window.
My mistake.
Just looked at one of Pauls old threads, the MYTH one, for class information. Looks like the D/Darts were H/S at the AHRA tracks. The "O" is option and it should be followed by a number. It shows up good on the side of the San Leandro Dodge.
