Series 2 EF Fairmont Ghia's had the full XR running gear, IE: 3.45:1 ratio diff.

You'll have to change the gearbox driven gear to a Black 23 teeth gear.
p/n: XE-17271E (around $14)

If you run 15" wheel's auto or manual you'll require a Grey 22 tooth Gear
p/n: XE-17271F


You could also Install a police cluster (hard to find) to be 100% accurate.
I have a couple if you require one!

Anyways, I hope this solves your issue.

Depends on the K's

Here is a recent one that a dozen people want, but none have claimed!

I have some very low K's (in Blackburn) that i want similar $ for but no LED conversion.

On the extension housing of the gearbox, 1x8mm bolt and the drive sender pulls out, then the gear is removed via a clip and replaced with the new one.

The red covered wire coming from th eleft hand side to the driver gear is a dead give away.

You only need to jack up the drivers side of the car to axcess it, and its an idea to chock up the car as a safeguard.

Should take all of 10minutes to replace.

If the car has the matching ecu,trans and diff why would you have to change the speedo gear?
