So what does it have stock? Is it a 3.27 non-limited slip. I would actually like the taller ratio for better mileage reasons but would not want to give up the limited slip. What do the aftermarket limited slip differentials cost? 600-700 dollars? Would it cost alot to get it installed?

First of all, "posi" is a General Motors term 
Second, all GT's still come with t-lock rear ends. The option you saw has nothing to do with it being an open rearend, it's strictly for the gearing. For 2007, all GTs come with a 3.31 ratio. The 3.55 ratio is now an option on manual tranny GTs. The only difference here is in 05 and 06 the 3.55 ratio was standard on manual tranny GTs.
