This site belongs to Greg, or RacerX, as we know him on this site, and he is, I believe a 2 time winner of the Sillver State Classic.
He is "into' corvettes and Turbo Regals, and if it is not his car, he probably can tell you who's car it is that you are reffering to.
Stan Davis owned this car. Last time I spoke to Nick at Duttweiler's about a year ago they were trying to sell the chassis.
Call them for more information 805-659-3648.
