I figured the highbrow route was better than, "You needs MaDd L33t MeTt4l hAxX0r SkIlLz, Yo!"

Take a look at the floor pan on the driver's side. Then look at the passenger's side. Now visualize making the passenger's side look just like the driver's side, but flipped left-for-right.

There's a drawing, I think on this site in the Tech Articles section, that has drawings for at least one or two of the parts that you need to fabricate and weld in.
