Odd codes on 64 Wildcat Trim tag

Hi guys, my Trim tag has numerical codes on it in the ACC section. I am aware that these codes are usually alphabetical, but my 4dr hardtop, built in Kansas City (BK) has the numbers "1-11" in this section. Everywhere I look there is no reference to these numbers for decoding purposes. Thanks to Sean on these boards, I am now aware that this was an anomoly that only occurred at Kansas City plant. Does anyone have any resource to decode these numbers? Cheers from Sunny Brisbane, Pat.

 

I suggest that you post a pic of the cowl tag.

I loved our time in your lovely city on the river.

 

Here is the tag, as you can see the ACC code is 2-11, (oops not 1-11 that my fat fingers typed originally!) Yep Brisbane is a beautiful city!!! I live further up the coast at a lovely place called Hervey Bay...world famous for whale watching!!!
Cheers, Pat
