Ahh, so all those numbers are cars manufactured for USDM? Aside from US and Canada, were they any additional markets that the SS/TCs were made for?
they were all made stateside too - so when I first noticed that the published numbers were only for USA cars I found it quite weird...
I mean other than small differences between standard & available equipment, most notably being the gauge cluster (KPH predominant);
- they are the same car,
- they're built in the same place,
- there always has been cross boarder migration with Canadian & American cars...
Congrats !
Did ya Poll It, BTW ?

Pop the trunk, lift the left side trunk mat, and look under it - there should be a sticker that lists all the build option reference numbers.
I believe LSD = G85.
Good Luck !

Yep .... 2010 the only factory option was G85 (LSD) . NOT having a sunroof is rare thou .... 80% of SS/TC's came with a sunroof ..... the percentage is the same for coupe's and sedans. I do not have a sunroof 8) and my car was ordered without a spare tire or jack .....thats the rarest thing about mine..... 1 of 11 8)
but apparently my source was mistaken;
the inflator kit was an option which replaced the spare tire.
there were 204 2009 ss/Tc's that were ordered with spare wheel not desired .
I don't really care for the whole 'option package' approach that the manufacturers are using these days...
I was told that one of the way s I wanted to order one, could have been done in early '09, had the Performance Division not been disbanded at the time...
I tired to get some 2010 numbers already, but have been unsuccessful with it...
