VERY difficult question.

The A would be a 69 GTS without question but what drivetrain??? Probably a 340 4 speed with 3.55s cause I would need one hotrod I could take on road trips, the other option would be a true 440 car.

The B is almost completely undecided I love so many of them couldn't even narrow it down to a Hemi Modtop 4 speed Daytona, a 69 M code 4 speed Bee or Runner (probably Modtop as well), a 69 Hemi 4 speed RT of either flavor, a 6 pack or Hemi air grabber Runner or X and that list could go on and on but would involve multiple carbs a 4 speed and a dana.

The C I just don't know well enough to know but chances are an Imperial from the 60s built to be the cat's meow on the highway.

The E is probably the easiest, a real 71 Hemi 4 speed Shaker RT with a 4.10 dana and a vicious day 2/super stock look.
