1) yes. from either ford or aftermarket. i bought one from ford recently. i would always go oe if poss, as they're a better fit. they may say not available anymore, or v. expensive. in that case, you can use a std one, as the only difference is the holes in the bottom rear where the side skirt holder rivets on

2) don't know

3) yes, either oe or a/m

4) don't know

5) ? what do you mean? the sidelight is just a bulb in the main headlight

6) don't know, but plenty in scrap yards

7) yes, oe only. there are 3 different brackets down each side that must be ordered separately in the right quantities. there is no kit of parts for one side. they are expensive, and difficult to fi without breaking. tip - warm them up with a hot air gun first
