You'll also have to make some brackets to drop your crossmember or modify it to clear the pumpkin. You can run without the crossmember for a while till you figure out what is going to work for you.
You'll also have to notch a little bit of the curve on the passenger side towards the front to clear one of the bolts.
You'll have to remove your steering center link to drop the differential. The ball joints can be a real beeeotch to break free. Start working on them days or weeks in advance to make sure that they don't end up stopping the process when you're already committed to getting it done in a weekend. Do NOT use a ball joint fork - go get a pitman arm puller & a BFH.
As I remember any more of those little tidbits, I'll pass them along.
