I have had to buy all kinds of shop manuals, catalogues, hot rodding manuals, history books, and owner tips to get this thing back together. There’s a lot out there, fortunately. The CORSA club is active all over the place and there are serveral large suppliers of parts. They are all happy to take my money. One of the best Corvair mechanics in the west lives in Golden. He is also happy to take my money, but it is well worth the advice he gives.
