Hey guys,

got my hands on an lsd diff with 3:23 gears my current setup is 3:08 I'm trying to work out what colour and number of teeth I need to get the correct reading (I have a T5 by the way) ford don't know they want me to pull my old one out any help would be appriciated.

My guess is....

You have the brown 20t gear for the 3.08 and would need the light green 21t gear for 3.23.

But i'd like someone to confirm this as i believe the data i have is for the BTR

You can look here for a reference .doc file that lists all the combinations.

Should also be in the FM docs too.. Light green it definitely is.
