I don't know about "currently available," but I believe that Monogram kit was a 2D, based on a slot-car body (it was a curb-side, right?)
IMC also made a 2E, subsequently re-released by Testors, and Aurora made a very early Chaparral roadster a LONG time ago (mine is around here someplace...).
Yeah, those Exoto die-casts are nice, aren't they?
Do yourself a favor and pick up a copy of Motorbooks International "Chaparral," by Richard Falconer.
