Default Still in search of a speedo sensor (3.9 swap)

Hello all!

Still looking for a speedo gear for my 99. Must be from a 99-03 6 speed car, as I have swapped a 3.9 diff in to the car. No one on the ~10 Facebook groups I am part of will remove one whole bolt and sell the sensor, only the complete trans... *eyeroll*

Anyone got one for sale?

Thank you!

I believe the blue ones are from 3.63 equipped cars.

I run a 3.9 in my 99 with 205/50/15's and the speedo is closer with the 3.9 on a green 4.3 speedo gear. Mine used to read about 4mph higher than actual speed with the 4.3 ring and pinion, now it reads about 1mph slower than actual speed. I just have to remember not to be unhappy when people aren't quite doing the speed limit ahead of me, but it is much closer now.

Interesting, I seem to have the opposite problem. I have the 4.3 sensor with 16” wheels, and at low speeds it’s pretty close. However, above ~50mph, My speedo is reading about 6-7mph slower than my actual speed. The gap grows slightly larger at higher speeds as well.

Interesting, mine might creep to about 2mph low at 70mph. It does look a little low clocking 120 though, I will have to pay a little more attention. Unfortunately all I have is a green one and a blue one, which I agree is for the 3.6 with 16" wheels.
