The copy of Bruce Anderson's book that I have, (2nd ed.?), is
filled w/ great information, but finding any of it would require a CIA analyst. As a reference book at your side in the garage during a rebuild, it is about as useful as the 2nd edition of "The Joy of Cooking/Sex/Cooking with Sex".
I consider it more of a great bedside read, like a Russian novel for Porsche geeks, w/ everything you would ever want to know hidden amongst anecdotal stories about wierd repair jobs seen over the last 40 years.
