Speedo gear question

[Vombil]

Hi guys

trimatic with 3.08 diff and 215/65/14 tyres.

everything I've read suggests there is no such thing as a green speedo drive (the one inside the trans/box). Mine looks very green to me!?

I haven't counted the number of teeth yet. Anyways it has a 25 tooth driven gear that was all chewed up and likely the wrong one anyways given tyres and diff changes.

Can anyone tell me what colour or tooth number driven gear I will need to suit my GREEN? drive gear?

thanks in advance IMG_5280.JPG

Green is 21 teeth according to the above.

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!!

Ignore the tyre size. Just use what was listed for 3:08 diff and trimatic. I doubt there is much difference in tyre height between yours and standard tyres anyway.
