Sorry it took some time to answer, I´ve been away for a while.
I used the Vanishing Point kit, as it has the chrome gas cap, rallye hood and the rallye wheels (I used Monogram rallye wheels however). The convertible boot is from the regular Challenger R/T (which has the shaker hood, and magnum wheels, besides some minor differences). The tires are originals from the kit, but I decaled with good year and poliglass F60-15 markings from revell Dart 69. I took the hemi from one of the 70 Coronets I have (as they come with 440 and hemi versions). The rear wing came from the Duster kit, because I think in the real cars if they aren´t the same, at least are very similar to each other. The hood pins are Detai master photo etched. Finally, excelent decals were supplied by Keith Marks.
I hope I could help.
