1965 1966 Mustang Books

A question that seems to come up on a fairly regular basis is "What books can I get that will tell me how my Mustang does the stuff that it's supposed to do, and how can I fix it when it quits doing what it's supposed to?" There are many, many books out there about the 65/66 Mustangs, some better than others. At the top of the must-have list is the appropriate year model shop manual. That's the book that Ford wrote for and gave to the factory trained mechanics that worked at the Ford dealerships, and were responsible for fixing these cars when they broke. Ford also put all of the wiring/vacuum diagrams in another book that they also sent to the dealerships. These two are essential.
You will, no doubt, notice that there is no 1964 Mustang Shop Manual, instead, there is a 1964 Comet and Falcon Shop Manual with a 1964 Mustang Shop Manual Supplement. How that works is pretty simple. On all of the stuff on the Mustang that is the same as on the Falcon, like the engines, for example, you use the Comet and Falcon book, while all of the stuff on the Mustang that is different from the Falcon, that's in the Mustang book.

There are also books that have a whole bunch of good, general information about the Mustang. These aren't critical, but they are very interesting. TThe book by Kevin Marti about the tags is useful when you are trying to decode stuff on your car, like the rear axle ratio, or trying to figure out how this car actually came from the factory.

There is no one book that has everything that there is to know about these cars, or, any single book that includes no errors. And yes, that includes the shop manuals. Even they have some things in them that are wrong. Fortunately, the errors in the shop manuals are so trivial a person could use that book for years and never stumble across one of those mistakes. But, this is why I have hundreds of books and Ford publications. It has always been my opinion that knowing is better than not knowing. That's merely an opinion of mine, a values call, but, it is the values call that I made. So, the more information I have available, the better. You can not possibly have too many books, especially about something that you care about.
