I have a 2001 Disco II and I'm considering swapping the headlights and blinker modules with a different year model. Possibly the 2004 or other. My question is fit. Since the body style is basically the same shouldn't I be able to do a simple swap? The '01 lights are 2 piece and the '04 is a one piece. Has anyone tried this and succeeded without having to do any major body mods to make it work?
