I am in the process of doing a 3" body lift right now.
I have already done the bed.
All I really had to worry about was the gas filler neck.
But I had an advantage...I took the body lift off of another LUV so I knew what I was in for.
My truck does not have a rear bumper on it, so I didn't have to worry about all that.
The real fun will be the cab. Hopefully I will get to that this weekend.
Here is the progress on my truck so far:

Hope this helps.
