Yenko,.oops, I mean a Yenko "tribute"

[tirebird]

While browsing through the current Hemmings Motor News(June), I saw a dealer ad for a 1969 Yenko(page #224). The Orange and white "Yenko" was offered for less than 60K. So, of course, it couldn't be real. Curiously, I went to the dealer's website and there, lo and behold, was the word "tribute". I don't know why the dealer didn't put that same word in the published ad, maybe they just forgot. But, online, they do have a full picture of the cowl plate. Does anyone know what this car was originally?
