[SuperCars]

By the nature of the invoice it would suggest that Harrell was not a direct employee. We can see the invoice was scratched out pertaining to his New Mexico shop, which suggests it was closed, but in any event the cars were not converted there. There is nothing in the file showing shipping or freight charges. It would not be cost effective to ship the car and miscellaneous parts, engine to New Mexico to do them. The Yenko Work Order has all the accessories and engine, parts invoiced directly as Yenko's portion of the conversion, with Harrell's labor listed as a sublet repair. The bottom line is that it's a Yenko work order meaning it was done in house at Yenko. This would suggest to me that Harrell performed the conversions at Yenko's shop perhaps bringing his race shop truck with his own tools there.

There is nothing in my file pertaining to Span Inc, ever having been involved with this car. I do have a "Yenko SportsCars" price sheet that is listed "Confidential" under it, the address is Box 277 Canonsburg, PA and dated June 7, 1967. This Price Sheet is for 450 and 410 Camaros showing factory options/codes plus aftermarket options with both the Net and Retail prices in separate columns.
