Default Diff Gears

OK just a question before i go and spend money on diff gears.
Lookin at getin 3.7 for my AU fairmont. Now as far as i know it has 3.23 or something like that.
Now when i fit my 3.7 my odo will be out, how do i fix that? Does ford have a speedo sender for the 3.7 gears like they have for the 3.45s?

Get a black speedo gear 23 teeth from memory and this will be as close as it gets.

About a 5-7 km error. You will be going slower than the speedo reads, but hey, that's a good safety margin I reckon! LOL!

Id say it would be 5-7 %, so 60 would be 55.8-57km/h when it read 60, and 93-95 at 100 indicated.

jaycar speedo corrector is probably the easiest and cheapest way, i know it can be done with a flash tune on ba's, but not sure on au's
