My old source (B&B Saab in the Bay area of CA) says they can't get them any more, and they asked that I remove them as a manual source. That's ominous (you might want to go in search of dealers who can provide manuals, and snap them up while they're still available). Bob Davis recommends Kachina Saab in Scottsdale, AZ.
And here are the part numbers of the more important manuals. These are from a list of available manuals that B&B sent me. When ordering manuals, specify the manual you want and offer the manual number, but verify that the number is current and correct. And let me know if you find any typos or if any numbers change. Also, please let me know of any additional dealers who can provide manuals.
