Welcome David, and congratulations on a sensible choice for the best city in Australia to live in!

Your background isn't in pathology by any chance?

Thinking out aloud - are there still significant challenges with engineer drawings and testing for hand built chassis and all mounting attachments. I remember seeing requirements not only for beaming and torsional testing, but dissected examples of welds, some dramas with door latch mounting points etc, etc.
At the time, destructive testing was required on sample fibreglass that replicated the body composition...!

I'm sure it's a labour of love for you, so it would be hard to sell it at this stage...but it would probably be the easiest option. There are always Cobras here on the second hand market at all sorts of pricing and quality levels, not to mention the option of building yourself a world standard Cobra from new when you get here.
