I just picked up a 1996 4.6L the other day (in addition to my 93 LWB). I can't seem to figure out which wheels I have. I am pretty sure they aren't original to 1996, they are 18s. Which turn signals and tail lights do I have? How hard it is too find the later model headlights (2001-2002?), and are they are direct replacement of the early ones?
