Well first off you will need the lights (obviously), then you will need a sawz-all. First thing you do is see where the taillights need to go, make sure the measurements are PERFECT, if not it will look uneven. Find out what has to be cut, moved, or reshaped. Do the cutting to accomodate the lights. Now the fun part begins. You will have to shape sheet metal for the brackets to hold the lights in place, then carefully convert/splice the wires for the new taillights to accept your old harness. Now that the taillights are in, you will have gaping holes around them. Now the REAL work begins. Go find a local metal shop with an English hammer and brake press for cutting metal, Start shaping the metal to fill the holes and after the hard work and labor its done. OH by the way, if you take it to a customizing shop to do this, expect to pay about $1,500-$2,000. This is just the rough overview of how its done. There are alot more tiny steps I didn't mention.
