That was my plan too DUDE! Then I got to thinking about how heavy those things are,and me with M.S. Good luck lifting it in place I thought...
Cheapest solution I can come up with is 3:91 gear all the time,and an 833 o.d manual. EVERYTHING else is $3000 and up. Talk about an exclusive market. Basically you only get an aftermarket o.d gear and save money on gas if you already can afford the gas.
