Thats my exact same set up. You need a 43 tooth gear. Mine reads maybe 2 mph (3.22 kmh) over gps speed. Heres the link to the one I bought but any should work.

Thanks BUFFY: Just Ordered it - According to my Speedo I would not want to be caught doing 140 Km in a 100 Km zone at approx 2300 rpm in 5th. Has anyone told fellow members you don't need a Cell Phone if you own a TJ ;o)

Dang those speedo gears have increased in price. I think it was around $7 when I did mine.

That Gear did NOT fit my NV231. I returned it a bought a FAIRCHILD D5039 43 Tooth Speedometer Gear; Blue from RockAuto.
