Below are links to some Fairmont 59 documents that I have found useful
1) Bulletin #359. An 8-page document specifically for the 59-C. Lots of technical details.
2) Bulletin #332A. A 4-page document that Fairmont provided when I got the "birth certificate" for my 59. Mainly it's a List of Materials
3) Bulletin #389. A 2-page document for the 59-D (with RO-C engine, and a few other differences)
4) An advertisement for the 59-D
5) Motor Car Collectors of America documents:
