I elected to do a frame swap rather than swapping out the front end. If you do the front end clip, you will probably want to change our your rear axle to a 5 lug so that your wheels will match. You will probably also want to lower and make less stiff your rear suspension to match what you are putting on the front.

Beyond that you will probably need to realign/reconfigure your steering shaft to fit the new steering box, and you may need to rework your brakes. There are some pretty thorough threads on this site and others regarding front end swaps.
