Chaparral 2A from a Chaparral 2B

First it is important to note that the Autoart 66596 version of the Chaparral is a 2B, as the 2A with a full set of vents in the front and in the rear plus the 3 front grid openings and the duct to cool the driver is identified as the 2B. The Autoart 66596 represents the Gr.: S+5.0 car #66, winner of the 1964 Nassau Speed Week with Roger Penske driving for team "Chaparral Cars Inc." and he did the 25laps in 1h 07m 25.12s

The following pictures depict next to the modified model the original Autoart 66596 to see how it looked like prior to be modified. To note that this version of the Chaparral 2A has no vents in the front and in the rear, less front openings (1 vs. 3), no duct to cool the driver and a smaller rear spoiler.

This is the modified Autoart 66596 that now represents the s/n: 2A -002 that won the GP of Canada at Mosport in 1965 with Jim Hall driving. The team was “Chaparral Cars Inc.” and he did the 100 laps at an average speed of 163 km/h.
