Bill,
Thanks on the bus connection. It was either Short-Line or Vanguard,
I'm not sure of any others, maybe Orange Bus Co.? But the Dart was there, in the bus garage (owned by a mechanic). Heard he ran the car
on the late-shift between the buses for fun, against the guys from the
night-shift at the Ford-plant in Mahwah. Maybe against some Super Cobra-Jets on a final test-drive, before shipping them out

Not sure if you heard of a Vic. Pomona Speed Shop, off route 202 in Pomona, NY. Not really a speed shop, but a 2-car garage behind his house (Vic's Auto Repair), with some speed parts in his side office.
Got the Hemi Dart in (74'/75'..??) from the bus mechanic.
