I had a few questions about the dealer accessory short throw shifter. On the website for 2010's it says it comes standard on the Se. When did that start, mine is a 2007 and I don't thinkit has it? Also if you install it can you still use the stock knob? What about the lockout ring for the reverse does the BM still have one? And anyone who has it installed did it make much difference, is it worth getting?
