Thread: water pump pullies

Can any one tell me when they changed from a three stud pully to a four stud pully on a 3.5 . I have a rr88 that had the plastic fan fly to bits and took out water pump timming cover for cam and radiator got it all together to day but on my over site the pullies and water pump stub is a miss match just trying to work out which way i should tackle this problem with new pump or chase after other pullies.
Thank
Dan

I found the info I needed, they sent me one for a defender
