Well, I finally got the parts in yesterday (while I was in California of course), but since I got home late last night, I busted them open and put them on today. So here'* the run down:
The part numbers above are correct, and thanks to GMPartsdirect outrageous shipping and handling charges, just over $500 to my door. So here are the pictures (my camera sucks pretty bad, sorry it'* all I had besides my phone).
Here they are just out of the boxes. They came with new wiring harnesses and bulbs, so that was nice.
Here is the old center and the new one, just so you can see that the reds are pretty much the same, just it looks quite a bit different without the grids.
Here they are on the car (sorry about the flash, but it lets you see the reflectors are only along the bottom of the light instead of the entire light).
Here they are again on the car (with the lights on).
Here'* some pictures of the car de-chromed with body damage on the front from a hit and run (hood, bumper cover and supports, headlights, plus it'* extremely dirty from sitting for a few weeks).
Another side shot without chrome trim.
