thanks WB. i am especially confused now! I counted 6 or maybe 7 teeth on the gear pictured above. strange thing is that 7 teeth (there is no 6 teeth drives) is either brown or red. So.... has my brown faded to green?! I've used an awesome calculator but turns out based on my diff, tyres and the drive in my trans, the closest I can get is a pink gear with 19 teeth that will still have me 10% out!!
