Ok. I am going from 2.73 to 3.42. I know this has been done many times. Can anyone who has done this tell me what combo of drive and driven gears I need for my speedo. I can't seem to find a combo to work. Is that like 80% difference? Can anyone help.

 

forgot to mention I am running the stock tires. But can you believe that I can't remember the size. They are not the 245/50's. Something like 235. Maybe somone will know.
