Great pics! thanks for sharing. Am I missing something, or do I see two fuel bowls on the roadster in pic #5?
Yes plenty of LHD cars here. Generally they can stay LHD (over a certain age) if they have been imported that way. I don't believe you can scratch build a LHD car here.
Should have made note that this is Graham Harvey a famous New Zealand race car driver over open wheelers and sports cars from back in the day, thanks to Tony bringing him along and introducing.
