Alrighty, I figured this would be the best place to go for this.
I currently have my Grand cherokee outfitted with a 6-ridge pulley on my power steering pump on a 7 ridge system. I pulled this one from a '97 5.2 ZJ in the junkyard.
We went to every single auto store within 70 miles. They all use Dorman replacement pulleys. Their 1.2" too big, and they don't fit the pumps in the first place!
Where can I find a non-Dorman pulley online or in store. I don't care if its a performance kit or a whole belt system replacement, I just need it to work.
