1969 Yenko SC Nova Info

[Dep]

I'm trying to find a description of what changes were made to the 1969 SS Nova to convert it to a Yenko SC Nova. I have a rough idea based on pictures I've seen, but I wondered if there was a post or somewhere I could go for specific information. I have seen pics of Yenko SC Novas with and without the finned SS hood inserts, for example. Also, has anyone written a detailed book on the Yenko cars?

Thanks in advance,
Dep
