Hello Yenko friends !!! I was hoping someone can help me properly I.D. these gauges? As seen in the picture the face of gauges say "sYc". The back of both gauges say made in the U.S.A. They have definitely been used/mounted in the past. The mounting holes show slight surface wear from slight over tightening. Very light pitting and light scratches. I was hoping to find out if these were Original to a Yenko Chevrolet? or are these some type of after market reproduction item? In my searches on a history of these comes up with nothing. It appears to me Yenko cars had Green face gauges. Any help or thoughts anyone has please throw them my way.
Thanks, ROB
