Which power steering rack?
 

My rack has been leaking since I bought the car 4 years ago and it is finally time to replace it. So I called Napa Auto Parts to make sure they had it in and they had several different varieties. They have racks that are performance suspention and non-performance suspention, manuel racks, he also said they are categorized by 1 bolt or 2 bolt (something like that, I don't remember exactly what he said) and lastly TRW racks. I thought all 5.0 racks were the same aside from the option of converting to manuel. Can you guys make heads or tails of all this? I figured that non-performance suspention was for 4 banger mustangs but he asked me the engine size before he gave me all the different option. But the 2 bolt/1 bolt business has me thrown off.

I was planning on doing the pump at the same time just to be thorough but is it really necessary? Thanks for all the help guys

We put a new rack on our 88GT and it was the performance model. The difference is, if I remember correctly, is the performance rack has a tighter turning radius - good thing. Not sure what they're referring to 1 or 2 bolt. Mine had 4-bolts total to remove not counting the tie-rod ends. 2-bolts for steering linkage and two bolts holding the rack up.

Make sure you get new tie-rod ends if you're changing the rack.

I went to Autozone to try and clear up some of the confusion. They have both the performance and non-performance, both with either 2.25 turns lock to lock or 2.5 turns lock to lock. What should I get? Any advantage to either? Thanks
