Interesting...Another local racer/enginge builder Ron Hutter owned Hut's Dyno ,TSE, and later Hutter Performance..he raced a 67 sponsered by DH Performance.At the very least the 67 was lettered on the rear qtrs (not in the usual script though).I have a few pics of a DH "Super John" car racing Hutter at Thompson.....as well as the Vega and a FG DH 70 Camaro FC.....Dick must have had some strong ties in NE Ohio.......Like to see the pic...I can post some more of the others later if anyone is interested..
