'05 Option Codes?

Is there a site you can go to for figuring out the option codes in the glovebox? I was curious as to the rear axle ratio in mine. I just bought it and it has the tranny cooler/towing package, the guy said he thought it had 3.73's but I'm just wanting to know for sure.
Thanks,
Matthew
