Here's some useful info that I used to decide what springs to use. Like Clyde said, it can be trial and error doing front springs. Ive had mine out/in 3 times now and hopefully hit on what I was looking for. Cutting springs just wasn't the answer on my car. rode like crap in the front and made my neg camber worse since I had the 5 lug swap. I ended up using the v6 w ac springs(5624) and 2" drop spindles. So far so good. If you cut, remember 2" cut = much more than 2" drop. I cut appx 1 1/2" off my old ones and put on reg spindles and it was lower than it was with the 2" drop spindles with the same springs uncut. So basically I put it back the way I bought it just with a slightly taller or not wore out springs. Not sure what springs it originally had but one was 13 3/4" and one was 14 1/4". I thought it was strange they were two different heights.
