Should be like 4 bolts for the main headlights then I think 3 for the parking and side lights... just use a socket and take them out and they should come out with the adjusting plates. Been awhile since I did mine so I'm not sure... someone else will tell ya for sure. I know it's not complicated.
Yup... There are 3 bolts for the head lights and 2 for each marker light... It's a tight fit in there with your hands and the wrench. I swapped mine out just a little while ago with the kit from 5.0 resto. If you have the same one, make sure that you have shims (metal washers) to get the fit just right..
The wrench size was standard if I remember correctly.
I don't you were asking to see mine... But I can show you the before and after shots to give you an idea of the difference that it makes to the front of my car.
Before (Yellow lights and a busted Fog)
After (before adding shims and adjusting the fit which I don't have a picture of)
Once you get them off, you may have to swap the headlight backing plates onto your new housings. That's not fun, but take your time and it will happen.
