identifying nickey cars, and yenkos, and...

[black69]

I had to ask this question, do all camaro super cars have tell tail builder marks hidden on them? I met a guy at a morris IL car show this past weekend with an authenticated black nickey camaro and the owner told me the car was signed with a special mark by the builder on the core support. he said the cars were not to be marked but in reality were in subtle ways. It made me think all cars maybe have builder marks on them, even yenkos, motion, and berger and dana cars? I am at the point that of the cars I run across, if I see 'anything' that is not exactly like the factory specs I will now wonder, especially in places it would serve no purpose other than a builders mark. had to ask.
