all you need is headlights and a s/ss bumper and it fits straight on, and if you wanna make it look like an ss you need foglights
headlights $200 from carsRus.com.au
bumper is aprox $370 from holden (you'd rather a plastic bumper)
and i found some foglights on ebay after i cracked one of mine for $120 for the pair
i love the look of a white vx SS
