Anyway for regular guys like us, having a repair manual from any of the authors will make do
. The important thing is to understand and have the right comprehension on what the manuals are trying to tell us. Mechanical or electrical instructions and processes have a reason why it needs to be done that way. The Chilton and Haynes manuals have already made short-cuts that do not necessarily follow the long route. If given the opportunity, try to browse over on these manuals and others. It will give a good idea on the difference in presentation and outline of good manuals.
