I wanted to put out some info. I'm sure you have seen the cost for a double V P/S pulley at team Grand Wagoneer...$99.95! I went to my local pick a part and found 3...each was $13.00. I also picked up a rear window switch (mine goes down but not up) and two hood stops in really good condition (which they gave me for free).
Check out your local pick a part before you buy online...it's worth the time!
Recently one of the bolts on the back of my P/S Pump snapped off (the one on the top right). I replaced the unit with a reconditioned one from NAPA. Turns out the reconditioned ones only have one (1) retaining/adjustment bolt instead of two, and cost $50.00. The new P/S pump works great even with the one bolt. However, your old hardware, for the rear post, will NOT fit on the rear stud. You will need to pick up a 5/8 nut, lock washer & flat washer.
