Ben,
I don't have any pics, but I can tell you this would not be a simple job for most people. The tail light housings are spot welded in to the upper quarter/bedrail, lower quarter, wheel house floor extension, and lower support brace.
Last week I had a pair that were to nice to scrap with the rest of the tub, so I just took a plasma cutter and removed them by cutting into the quarter and floor sections.
IMO, you need to decide weather to fix them on the vehicle or junk them. If you junk them, cut them away from the adjoining seam by cutting on the side of the tail light housing. You will then need to drill and grind at the spot welds to remove them from the other panels.
FWIW, another member here on CB was interested in the ones I just took off since the repros he just bought were junk according to him (I have not seen or tried the repros, but have heard the same elsewhere). With that said, make sure the ones you have really need replaced. It would suck to go to all the effort to find out that the ones you replace them with aren't what you expected.
