I am using a steeroids rack and have not had any problems. I think it is a great kit and has worked wonderfully for me. The car tracks straight and feels tight. The one improvement I made was to use a GM saginaw pump. My Ford 5.0 seemed a little quick and easy. After changing to the saginaw the feel of the car improved.
I still haven't had any problems with my setup. I purchased the pump later and from a local auto parts store. I had to make a bracket for the pump because I had to mount it on the drivers side below the alternator which is on the driver's side head. As you know I have alot going on in my engine compartments so you won't have to do all that custom stuff. If they sell a GM saginaw pump and bracket with a kit then get it. If not look into March Performance and some of their brackets.
