You'll need to do this:
Jack up the front. I use the front lower control arm mounts at the body side.
Put jack stands underneath for safety (read: your ass!) sake
Put the jack under the front axle, loose for now. Just barely supporting the axle.
Disconnect the front sway bar end links (17mm socket and wrench, if I remember correctly)
Disconnect the track bar bolt at the axle end (21mm- you'll need a 1/2" breaker bar to get this if you're using hand tools)
Disconnect the shocks (2 5/16" wrenches on top, I think 17mm on bottom?)
Take off the brake line brackets inside the fender (10mm socket)
Use your jack to lower the front axle until you can pop the springs out. Install the spacers as per the instructions, and re-install everything in reverse order. Do about the same for the rear, and you're on your way.
Where are you located? Maybe there's someone on here nearby who's willing to help you. It's a really easy installation- you're likely just psyching yourself out. It'll take a full day your first time, but you'll feel good knowing you did it yourself, and saving a couple hundred bucks is great too
Enjoy! Mark W.
