X11 X22 X33 X44 ect
 

Can I get some pictures please? I'm more of a visual guy than a reader.

What would you like to see?....Joe

I'm not going to speak for the original poster but maybe he's referring to what they are, could be? I know X33,X77 are Z's. X22,x66 are big block cars etc., but the X44,X55 are a little confusing. Some Copo's are X44 some X66's? What were SS350's coded? Maybe I'm off base here.

Well there you go. Back to our regularly scheduled program... Thanks Lee.

Maybe OP will jump back in but I took the question as photos of the trim differences, I.e. quarter gills, wheel opening trim, etc. looking for pics of cars with those differences?

... Could an X11

... be a COPO ?

... :confused2:

... Just checked that sheet .... it says some were !

All X11 indicates for certain is Style Trim Group [Z21]. Included with Rally-Sport.

Virtually all COPOs with Z21 will have X11 tags. Several ZL1s are X11.
