Ken,
Yes the Valiant Charger is an Australian model only. Some were exported to the UK and South Africa. I have seen on some web sites that they are in the USA as well but more than likely imported by the owner. They are an A Body construction with Torsion Bar suspension. Its about 300mm shorter than the Barracuda but some 300 pounds lighter. It is 265ci or 4.3ltrs Mine is doing 300hp with the webers.
Cheers
Damian
