Re: Speedometer Recalibration
I'm guessing 39 teeth (GREEN 52068061):
http://go.jeep-xj.info/HowtoSpeedoGears.htm Some say the speedometer
gears are the same between the Dana 300 and the puny New Process 231,
all I can find out is there is a short and long shank, and that the
stealership will order the Dana 300 gear. I would give the job to your
local speedometer calibration shop, there's one in every town feed by
people trying to weasel out of their speeding ticket.
