Cheap options for fixing the AU1 forte are:
1. Using the grille from an AU2/3 ute. Looks tidy when painted body colour.
2. Using the grille from the Hawk body kit (for AU1 sedan or AU2/3 utes). Sydney Special Vehicles part num is 1127 but go to http://www.ssv.com.au
and search for 1126 (which is the front bumper). You're looking at about $220 for the grille painted.
