G'day Dick, I must put brain in gear before opening my mouth. I don't know what car it is but it is a good looking bit of kit. see you at Wakefield.
Could it be the So-Cal Special? I have a memory of it being there (it's on some home movie footage my uncle took) and I seem to remember Dad telling me it had a Holden engine.
But if I'm wrong, try to remember I was only 8 years old at the time!
