Well from experience:
It goes on the bottom. Did you get the longer stud with the spacers? You will need one of those.
The nut that holds the bottom of the spring is kind of a bear cat so soak it real good. Then be sure to tighten the bottom nut again after you drive it a bit, they tend to loosen a little as the spring gets seated.
Here are some pics of mine so you get a little perspective.
in the 2nd pic you will see that I used a socket instead of an end wrench to get the nut off. I just put my 1/2" ratchet through the spring and it made quick work. Then I just used my magnet to pull it back out through the top of the spring before bolting the top side back together.
You will need to drop your radius arm waaaaaay down to make room for it. Be sure to get everything unbolted before doing this: spring, shocks, caliper supported ( I didnt have to take mine off bc I have extended break lines), sway bar, ect.
YOU WILL NEED AN ALIGNMENT so be sure to have about $150 bucks ready. They will need camber bushings to get you back to par and often times charge $20-40/side for the bushings.
Any questions just let me know.
