Unless they became much more complicated between '97 and '03 (and I am sure someone will chime in shortly if they have) it is a breeze. It should only be held on by two bolts. Disconnect the negative wire to your battery, and then the two wires connected to the starter. Take out the two bolts. Swap starters. Reinsert two bolts. Reconnect wires. Go for a nice long drive to relax after surgery.
