This "blue book" is the bible. It contains real pictures of each assembly, complete instructions, teardown and assembly. If you find yourself stuck, e-mail me at fred_sheffield@hotmail.com and I can scan and send you whatever you need. Or, a 50 buck deposit and you pay shipping and I send it to you and reimburse your cash at the end, if you ship it back. These things are precious to a rebuilder.
