Hi can Anybody tell me the number of teeth on the pinion gear and the crown wheel that are used to get the 3.64 ratio ?

 

Front or rear diff, and why do you need to know this? (as I'll have to tke a cover off one to count them), maybe I can give you advice without doing this ?
Obviously you must use the same Front and Rear on a 4X4 Car.
There is a 3.9 ratio which is from the 2.0 Sierra 4X4 which I am using in my Puma 4X4 Front 3.9's are getting hard to find now

47/13

i've got 2 of the front diffs and no one wants them, even for free

 

What 3.9 fronts ??

I'll have them off you if so

Cheers Dave

 

The reason I ask is I am doing a 4x4 conversion on a MK5 cortina and I am thinking about using the original rear axle and a quaife ATB diff. So I am trying to find on the teeth on the pinion and crown wheels on a 4x4 cossie diff so I can get an identical set for the atlas diff.
