I have seen people buying all the parts as some have mentioned. Tie rods, pitman arms, idler arms, etc. I have heard a few others say that they only changed the center link. So that is what I did. I ONLY changed the center link. Everything else fit perfectly. It was easy to align. Nothing rubs. An excellent modification in my book.
I took the power steering off because it does create drag on the engine. It weighs a lot as well. It has really cleaned up my engine compartment too. I race my car occasionally and have lightened it a good bit. Aluminum intake, heads, water pump, no accessories, etc. With the front end being light on these cars the wheel is not hard to turn at all. With all the leverage that these big steering wheels create, it is no problem. And I have 225/45/17 up front as well. So they are not skinny. Only if you are sitting still and want to turn the wheel is it hard.
I used to have an 89 convertible that I used to bypass the power steering on at the strip. Now that was VERY hard to turn.
