Part numbers vary. Over the almost decade these were made, there were a few different part numbers for the same thing.
The fog lamp itself it the same assembly across all models. What differs is the panel it mounts into.
I though I had some pictures from when I did my Calais foglights when I painted the front bar, but I didn't.

As mentioned, these names only refer to the inserts, not the fog light. The two types are A and Type B. They bolt to the different panels the same.
The fixings here are torx head, but you can use any other just fine. It was M6 or M8 from memory. M6 seems about right. They are the same as used on VZ (GTO), so I can check the length later for you.
