This is in response to my post of a few days ago asking how to get my speedometer accurate after going to 31" tires. I have an 01 with the 2.5,5-speed, 4:11 gears and 31" Goodyear MTR's. Vlad, and others have said to go to a 37 tooth speedo gear, but Quadratec in their chart, indicate I get a 36 tooth. Which should I go with? Thanks
