To use that front bumper your going to need the genuine headlights and brackets, it wont work with the aftermarket 'Twinlight' setup.
How much were you quoted for a genuine XR6 front-end conversion? Last time I heard it was $1200, probably abit cheaper without the headlight surround/grill, but youd be still looking at well over $1500+ all up?
