If I'm not mistaken, that's Chaparral 1, not a Scarab, in the Meister Brauser photo. Harry Heuer (of the Meister Brau family)was running both a Scarab and a Chaparral at around that time, frequently at the same time. IIRC, the Scarab they ran was RHD, and is the one currently owned by Augie Pabst. That particular Chaparral (I think that Harry Heuer's car was the second built, the first went to Jim Hall, naturally) has since been restored and vintage races.
Sorry for the thread hijack!
