Mate, dunno how I failed to mention this, but I’m great mates with the bloke who built and provided all the Cars for this Movie! 
He now lives here in WA and has told me so much about the makings of this movie and all the vehicles that were in it.
He’s still got the original number plates off that 57 Chev attached to the Bar in his shed, and has since built a similar 2 Door 57 in the same fashion, but in a different paint scheme.
The “Fox” Dodge is also here in WA and I have seen it many times, still looking exactly the same as it did in the Movie.
Interesting little facts I’ve learnt from my mate, like the “Gazzard Boys” Red EK HOLDEN that gets rolled in the movie is actually an FB HOLDEN that they fitted it with an EK Grille/bonnet etc, as those were the cheaper parts available from the wreckers at the time!
If you know how to pick the difference between these models, I highly recommend going back and watching the movie again, as I did, to spot the difference that I had NEVER realised prior to him telling me that story!
Another trippy fact is that my mate and the other mechanics who made the cars for the movie had a FAT old time when the movie was eventually finished and released in Cinemas long after the filming had finished.
They would all roll up at every single Drive-In Theatre in the Eastern States with the Fox Dodge, 57 Chev and the “Rammer” for each Debut Showing of the Film.
He said it was PRICELESS with him and his mates all parked up watching the Movie in amongst the the rest of the crowd, then seeing people’s reactions to realising that the vehicles they were seeing on the big screen in front of them were ACTUALLY parked right alongside them! 
He said every single showing that they attended ended up in them rarely ever getting home those nights, as many conversations were had, and many beers were available out the back of many different car boots to keep the interactions “flowing”. 
I’ve seen hundreds of old Polaroids that he’s kept in quite a few Photo Albums documenting the builds of every one of the vehicle’s seen in the movie, right down to the old Farm Truck that the Flaming XY launched off from into the creek…one of many XW/XY’s that they had to build for the Movie when you consider how much drama that Car Character went through!
There’s also a lot that I’ve probably forgotten too, as staying weekends at his shed talking about these old times usually equates to too many beers, not enough sleep and too many hangovers to remember half the shit we had talked about the night before.
