Yenko paperwork for creating the COPO option?

[YENKO DEUCE REGISTRY]

Ditto that! I know we've kicked this around before, but I firmly believe that the Yenko deuce was a Boss302 knockoff - Don loved road racing, and if he could sell enough of the deuces as insurance beaters, drag cars, streat cars, whatever.... to get them qualified for SCCA, then he would have been happy. Don wanted to run with the big boys in '70, and the SCCA guys all had 'their' own car - Shelby, Gurney, Donahue, etc... the deuce would have been the Yenko of the SCCA muscle car class!

That pic that Howie found of the deuce with the stripes installed BOSS 302 style was the clincher

I think the turbo Z was another attempt at getting his name back into SCCA racing - albeit half heartedly, as Kim Mason appears to be the main driver behind that effort.
