Chilton is a waste of time. Get the 1968 Pontiac Factory Service Manual. It has been reprinted and is going for around $50. Even less used on Fleabay. The 1968 Fischer Body Service Manual is also a must. It covers the convertible top system better than the FSM. With these two books there is nothing you can't do on the Firebird. A little harder to find is the 1968 Diagnosis Manual. It explains systems in more detail and makes it easier to track down troubles. Luckily for us these books have been re-printed and are very available so it is easy to have the important information right at your fingertips.
