You "believe" and you "think"?
I was not at the Dealership in 1966 and 1967, but have certainly spoken and interviewd more than a few people who were close to Dick, Bill Hielscher as well as having assisted Guy with Bill's Race car, while at the Nickey Dealership. All thier info seemed to corespond. In the spirit of accuracy, why don't you tell us what YOU know to be the facts.
The pages above are from an article about Nickey Chevroletin Chicago's 427 Camaros. If I recall, some of the Camaros have no Nickey specific badges other than the Nickey Crest on the tail panel...which all cars sold out of Nickey received.
