Also: I had two marker lamps out on the top rear of the van. One was smashed, the other full of water. The design does not allow it to be cut apart like the front markers, so I just ordered replacements for the two. They came is as different manufacturers and were just different enough that it took a great deal of effort to make them work. The plugs are different, so I had to splice it in. The old screws had to be exchanged for longer. They ground through one of the screws, which go through a metal plate behind the fiberglass. The originals had a brass ring which facilitated conductance through the screw, but I had to cut a slot in the face of the new lamps so the ground wire ring terminal could sit under the screw head.

To cut the slot, I used a high power soldering iron with a plastic cutting / melting tip. Then I followed it up with a utility knife to clean it up. Worked out fine, but I would have happily paid more for the exact replacements.
