What are you suggesting Bleh, a Honda transplant?? For shame, don't even think of it! Even if you don't restore the car anything close to mint Iroc, at least you'll have the pride of knowing you saved an oldy.
Finding parts for a 60+ year old car will always require a fair amount of searching, especially when you need everything. May I suggest Hemmings Motor News, it comes out monthly. They don't call it the " bible of the collector car hobby " for nothing either. If you are undertaking a major restoration and looking for parts, or just looking for a ride, this publication is invaluable.
