328 parts
If my memory serves me right the factory in East Germany was taken over after the war by the solviets and they built the 328 and I believe they called it an " Eisen", but don't quote me on that. If someone in Europe could do some snooping for you, you might be able to find some parts that way, as I recall the cars produced were identical to the 328s, there was also a derivative of it built in the UK as I remember. Mechanical parts can always be reproduced but they are not always as resonably priced as we would like them to be. Body parts can also be made up but finding someone with those talents can really try one's patience. Good luck with the project and keep us posted, sounds like a lot of fun if you're so inclined.
