[YENKO DEUCE REGISTRY]

For comparison - Vince Emme started tracking the Yenko cars in the early '80's. Of the 201 '69 Yenko Camaros, I believe he has confirmed ~130 of them.

I started tracking the Yenko Deuce Novas in 1996, when ~30 of the 175 were known. Now, some 15 years later we are up to 87 cars known.

So, registry efforts do start off small, but when there is a lack of supporting documentation it makes it very hard - and extremely risky to actually put something down on paper.
