If you can find another adapter let me know, Ill take it off your hands. Im going to total up how much it would cost me to run the cooler setup i want and see what the price difference is between it and the KB setup and make a judgement call from there.
On the gearing, in order to keep stock ratios Id need a 4.2X gear, so Ill sacrifice a little highway mileage for more pep out of the hole and better towing mileage since Ill be able to use 6th pulling my 5er running the 35/4.56 combo. Ive talked to a couple people who are running that setup and all of them are happy with it. Plus in my civilian life I have a company truck to run errands in and the army pays my way for when I have to go do stuff for them so mileage isnt too huge of a concern.
