Okay, so what can you do to it? Well the first thing would be wheels. Up until 1968 the Amazons had a really weird stud pattern on the wheels which meant they were difficult to get alternative wheels for, HOWEVER, in the last two years of manufacture (1969 and 1970) they had a 4 1/2" spacing, the same as American Ford Mustangs etc. This car is a 1970 Amazon, and I've had the stud pattern measured by North Hants Tyres who confirmed it was the 4 1/2" spacing. This means you can get pretty much any wheel on 'em that you like! Nice! Once you've got some nice big steel wheels on it with whitewall crossplies, then it's just a case of getting airbags put in and have the roof chopped, (sloping back to give a fastback feel) to make it look like this:
I was then going to add trim from the side of a 1953 buick to finish it off:
So that's it, wheels, airbags, chop and side trim and you'll make an already excellent car into something unlike anything else you'll see on the road or at a show.
