The Walters Yenko was sold new at Hugh White Chev. in Columbus, and it was RG. They are now a Honda dealer. Ed C. had a pic of the window sticker in his book. Bobb is still in business at the same location. They MAY HAVE sold a COPO car, but it's not documented. A guy in our Camaro Club has a Bobb '68 BY 'vert L78 with 1800 original miles that was a drag car. Very well documented. They sold a lot of Hi-po cars. Walters is 5 miles east of National Trails, and about 35 miles east of downtown Columbus.
Bob McDorman is now in Columbus, but only because they moved the city limits. Jack Maxton is in Columbus, and sold some COPO Camaros, one X-11 Tux. Blk that I'v posted a pic of. Altough not famous for it, Columbus guys like to street race!
