I got a rebuilt pump from NAPA but had to replace it twice. The 1st one began leaking after 1 year, and the 2n one was way too loud ( a howler as they say). I had troubles with the pulley because of it being worn which was a real hassle. I searched all over and finally did a Google search and found a new power steering pump pulley from Mustang Parts House in Dublin, CA @ 1-800-956-8782. I paid $69.00 with shipping, but it works beautiful!
