I have a 98 GMC Jimmy, and find the way that the headlights attach to the body to be kind of half assed and all of the hassle that comes along with getting them back in is a pain. I was thinking of changing my headlights and grille to the sealed beam headlights and one piece grille, except I will be using a 9005/9006 to H4 conversion harness and H4 conversion headlights instead of sealed beams. Does anyone know what else is needed besides the actual grille, headlights and wiring conversion?
