Daryl,
I think Mark J posted that when Tim Hennessey got the car, new quarter-panels were on the car (standard units). He replaced them with Hurst
replica units. I think thats what he said. As for the Mt. Kisco apartment complex. Barker Street is an area where that sounds. Several gear head guys lived in that area. A short walk to Ritchie Mattoni's Professional
Machine Shop, off Maple Avenue

As for Charlie Castaldo, saw him alot from 68' thru 72' at Dover. Not so much after 73'. Lived in Scarsdale, near the Yonkers border.
Yes, he had only (2) Hemi Darts. The two car reference that someone mentioned pertains to 1970. Charlie had the Hemi Dart and a 70' Hemi
Challenger that ran in SS/DA. The Dart, I think ran in Pro/Stock for a very short period in 70' (The 68' car qualified for Pro/Stock in 70', and in 71' if you retro-fitted the front grille and light hardware with 69' Dart units).
I know Charlie was at the 70' S/S Magazine Nationals at US30 York in May 1970 and the NHRA SummerNationals in July, also at York.
