The front bar will fit up no problems.
You will need to the chrome bonnet extension bit that goes between the bonnet and the grill.
Or you could use one from a HSV, and have that colour coded as well.
I dont know how much wiring is required for the Spot/Fog Lamps though.
Painting can be anything from $200, through to $500, depending on the condition of the bar, and who does the work for you.
