Here I am!
Snibble already answered your questions about the light replacement. Very Easy. Yes you still have fogs, nice bright white fogs (not yellow like the DOT lights) but can be yellow if you can find the cadmium coated H-3's or adapt the yellow cup from the DOT lights.
What you see in my picture are the city lights as they look in the day light, they seem much brighter at night though.
The US wipers can be used, but an adapter need to be made to mount the wiper motor in the correct position. Not truely correct for the purist, but I don't mind the look. I used pieces of perforated strapping, mounted the wiper motors to the strapping, then bolted the strapping to the bottom of the light buckets. The Euro wiper postions is a little off from the US position and without an adapter they wont work.
The trim panel has one phillips head screw accessable when the hood is open. The other end takes an odd sized 6mm. You access it by removing the side marker assembly. Not much room to use a box end, but can be done with one if you're not in a hurry.
Hope this helps. I'll be out of town for a few days, so I won't know the outcome till Monday.
This is what the fogs look like:
