Once again, the Monogram-MRRC Chaparral is NOT a "2C" but a "2". The 2C is a completely different animal, the only modeled examples being:
1/ the very poor vac-formed 1/24 scale MRRC body from 1968.
2/ the very poor 1/32 scale Eldon abomination.
3/ the very nice LS (now ARII) 1/24 scale model.
4/ a lone 1/43 scale white-metal/resin kit by SMTS.
The sole 2C only raced 4 times and was transformed in the first of two "2E" in the winter of 1966. The 2C was based on a GM-designed alloy tub from an experimental car called the GS2B, designed by Larry Shinoda snd Bill Mitchell. This very car has now been restored and looks similar to the Chaparral 2C because the 2C was...inspired by it.
To confuse the easily confused, one of the Chaparral 2s received modifications making it appearing SOMEWHAT like the 2C, by adding fins and a moveable spoiler aft. This car, driven by Hap Sharp, only ran once in this configuration and won the LA Times GP at Riverside in 1965. It features louvers all over the front and rear fenders. The 2C was devoid of such louvers.
Calling the "2" a "2C" has been done for years, and the many corrections made on the subject do not appear to have landed. The cars are visually VERY different, so one would think...
