Replacing my speedo gears and was wondering how many teeth i need. I have 5:29 gears and 37s. it's a 1991 toyota 4runner. Thankyou!

 

I had portland speedometer service build an adapter for my '85. You just use mile marker signs to measure your odometer reading over ten miles, give them the info, and they build a little box that goes between the speedo cable and the tranny.
