I got my speedo gears from ford. I They will work with the cable on your car, You may have to re-route it to the other side of the trans though. It may take some playiing around to fine the right gear for your gears/tires etc. I never got mine right, I have 4.11 gears and i have the red gear with the most teeth i could get, and it still is a little fast on the speedo. I need to change the gear on the output shaft, but i have never cared nor had the time to fix it right.
