Dont know if the 95 is exactly like the 94, but the 94 you unhook the electrical, then take off the bracket (2 bolts) with the fog light attached, and don't lose the u-nuts that the bolts came out of. You may need them for the new one.
When you get your new one on the car, the aim is supposed to be such that the top of the bright spot, when shone on a vertical wall 25 feet away... is supposed to be 2 inches below the hieight of the centre of the light on the car. On mine, I ran out of aming room on that bolt, so I cut up an old rubber floor mat to make "shims" between the aiming nut and the bracket.
Aim is expected to be done with 1/2 tank gas and no load.
For rust, I have used this:
It'* expensive, but goes a very long way... 4 ounces will probably do a whole door..
Especially great for small surface rust area. You remove only the loose stuff, leave some rust. Thr product comes like milk, and chemically turns the rust black. A couple of coats will end up like a thick black "primer". You can sand that down and paint it.
Did a large area on the inner rear door of a 94 three years ago and it hasn't moved since.
