I did the 3 inch body lift on a 2002 passport. basically the same as yours. Turned out nice. Tokk the better part of a weekend though with some help from some friends. Started out with 2 of us working on it and then ended up with 4 people and we worked in 2 differnet groups on seperate tasks.

that kit will fit yours not many parts will be used fron the kit except for the bolts nuts and pucks. You should go ahead and get some hardend steel washers for it as well. The kit ones bent on me after about a month. I eneded up having to rplace them although it did not take long cause I just did them once at a time. Le me know if you want a write up on it that I did. Basically a checklist that is pretty step by step to follow.
