As kaydenver pointed out, you're better off with the spring replacement (as Koni and Bilstein use). They use the stock spring location, and are very easily adjustable. I have the Koni/TC Kline version of those.

I've also seen cheap one piece struts with spring built in, that you remove your existing spring, and use the spring integrated with the shock. I'm not a fan of those, since it puts extra stress on the rear upper shock mounts, which is already stressed, and a location that it's already a great idea to have reinforcements on.
