Outer Limits 4x4 Board

Ok so I picked up a pajero pto this evening . What I did not do was count the number of teeth on the gear that drove the pto . This looked like the input gear in the t/case . Can anyone tell me what the number of teeth is so I can start working out ratios it all drives at .

I am not sure if I will use the pajero pto bit so trying to work out the speed it drove at .

Cheers
Chris
