There it is, riveted to the driver's side door jamb; the official Yenko plate issued by Yenko Chevrolet of Canonsburg, PA. "Yenko-izing" a late model coupe is exciting enough. Having your conversion recognized as "official" is a rare treat, and if my information is correct, is impossible today. As there were only 185 Stingers built by Yenko Chevrolet, and only a handful of Stinger plates sold to qualifying conversions afterward, the value of the originals and recognized conversions has risen over thirty-some years since they were first offered to the public. It's logical to assume that as time passes, their value will continue to escalate.  

For street and show, YS-317 is equipped with B.F. Goodrich Comp T/A, 215 R60 -14 tires mounted on 14 x 7" alloy wheels. For the autocross, Herb mounts Hoosier Autocrosser, 235/45-13 bias ply boots, mounted on 13 x 7", widened Corvair wheels with a 3/4" negative offset and double centers. More detail on the suspension components and settings follows on the last page of this feature.

Below, note the built-in tow bar brackets under the front bumper. The brackets are also used for the quick, temporary mounting of long range driving lights for Monte Carlo style rallys.
