There are several places in Phoenix that do spring work,the catalogs usually have listings in the back that will give you coil height,diameter, etc. look up your springs and go from there to find a taller one.You might be able to go thru NAPA for a better price,go to the main store at 28th Av & Thomas you'll have better luck.The other alternative is a spring rubber it looks like a big black donut they should have those too,jack the car up slip it in like the roundy-round boys do and it's done,maybe you will get off cheap and lucky too.
