96 head light conversion
 

Does anyone know if you need to change the support and pigtails since it already has the composite headlights and bulbs or if I just need the 98 valence, bumper, grille and headlight assembly

You'll need the newer core support

Thanks. I'm hoping I don't have to cut and splice stuff.

Well, depends on what headlight assemblies you get. Some aftermarket assemblies have two bulbs in the turn signal housing underneath the headlamps... all you need is a couple tap splices. No big deal. You might also want to shorten those wires.. it's a bit less distance from the headlamp housings than it is to the bumper. Couple butt connectors will suit you just fine.
