As others have said, that readylift video is very helpful. Don't even bother with Fat Bob's instructions and just follow the video. However, there were three things stood out as being a pain when I installed my Fat Bob's lift.
1) Rotating the top of the front struts in order for the spacers to align with the mounting holes properly. I borrowed some coil spring compressors in order to do this and you will to unless someone can point out another way to do this. Have some on hand when you start otherwise you'll have to put the install on hold like I did.
2) Removing the old rear shocks was a pain because the shock shaft can spin freely when you try to remove the nut. If you don't intend to keep the shocks, then you can just clamp down on the shaft with some vice grips when removing the nut, or cut the shaft. Since I wanted to keep the original shocks, it was a little more time consuming for me.
3) Installing the longer/beefier rear shocks proved to be very difficult because the bushing at the bottom of the shock did not want to fit in the mount. I had to trim some of the bushing material to make it fit.

in my build thread for pics of each of these things I mentioned. Knowing all of these things prior to install would've saved me a lot of time. It really isn't that difficult of a job but these 3 things slowed me down the most. Hope this helps. Good luck and post pics when you're done!
