I just purchased a 2010 R/T with the 6 speed manual transmission. The dealer having lost the window sticker before I picked it up, I won't have a replacement for a couple of weeks. Without it, I don't have all the detail as to how it's equipped. Anyway, do all the 6 spd 2010 R/Ts have the same rear end gearing? What is the ratio? Feels like mid/upper 3's. Thanks.
