There are sellers out there offering copy parts such as lights. I recently bought original style side repeaters for my 275 project, from an ebay seller based in Italy for about £60 inc P&P. Same goes for the circular rear lights, I found another seller in Italy who had them in stock at a reasonable price, about £120 inc.
Most of the parts can be found for reasonable money, just depends how much of a compromise you are happy with on your finished car. You can do things with the windscreen to make it look more period, look at the Grassbank cars.
