Can someone tell me about this four speed that was taken out of a Yenko 40 yrs ago?

[RobR]

I thought X-66 cars had the chrome 1/4 panel gills/spears?

[jdv69z]

Correct, all SS Camaros received the quarter panel gills. Unless I am mistaken, X66 did not receive chrome around wheel wells, bright drip rails, etc. The quarter panel gills are the reason X55 was used for small block SS Camaros, I believe. Otherwise, they could have been built as X44's.

OK, thanks. I wasn't aware that the SS got the gills no matter what. But this car would have been a COPO wouldn't it? Not a SS? Or is someone saying that this car may not actually be a COPO, but a SS with Yenko stripes added?

This car was a Yenko, the picture was taken in 1978 and he had had it for a while trying to decide what to do with it. It was in ruff condition and he wanted a show car. When he saw my Camaro at a car show he made a deal and bought it and took the M/T and all the emblems from the Yenko and put on the 69 that I had.

X66 trim has the 1/4 panel spears.

"As can be seen from the table above, the X11 code always includes the first four features: the use of black body sill paint and the use of the trim moldings (rear quarter louver, driprail, and wheel opening). The difference between X11 and X55 is that X55 does not apply the driprail and wheel opening moldings.

From this table, we can deduce that the wheel opening stripes, headlamp bezels, and taillamp lenses were not a factor in the X-codes. The table also show that the addition of Z22 (which eliminates the bright taillamp and headlamp trim, since the Rally Sport lamps are different) has the same effect on the X-codes as Z21.

Going back to the X22, X33, X66, and X77 codes, their meanings are now clear. X22 and X33 codes have the same meaning as the related X11 code, but with an added blacked-out tailpan for X22, and with an added Z28 stripe for X33. The X66 code has the same meaning as X55, but with a blacked-out tailpan. The X77 code has the same meaning as X44, but with a Z28 stripe. Including these meanings in a table covering most of the major trim features for all of the X-codes, and adding in the related Z10 & Z11 codes, we get the following result:" copied from CRG site.

I'm sorry, but I'm not understanding why this car would be a X66. If it's a '69 Yenko then wouldn't it be a COPO? And if it's a COPO, then wouldn't it be a X44 or X11? What am I missing that would make this car a X66? Most of the people on this sight know more about these cars than I do, so I'm trying to learn from you.

[Stefano]

Some of the early Yenko’s were X66 Camaros.

[big gear head]

OK, so converted cars, not COPO.

[Stefano]

X codes are 1969 Model year.
