How can I tell what I have? Steve said my old spring were sagging that's why it looks different. I have photos from when I bought it new and over the years I cannot see any big changes. Also I could never get a regular floor jack under the car I had to buy a low profile racing jack but now I can slide my suv 3 ton jack under it. After driving it more it is no where near as stiff quick lane changed and tight turns the car/body roll is so much worse and not tight like before.
