Theres a complete VR Stato from sale at Imlachs self serve wreckers, on centre rd in Springvale. They're asking $1600, its straight and its got a caprice grille as a bonus.
Also you can buy a new bar from Holden (unpainted) for around $400. Also worth keeping in mind, that VR/VS Toyota Lexcen gaurds are interchangable with VR/VS Stato and are plentiful at wreckers. New grille's are also availible from Holden. The only tricky one is the bonnet, keep an eye on ebay.
