The Helms book is probably the best for repair info anywhere. You can get a service manual from them in either book form or CD from there site>>helminc.com. Just look under the repair manual section and follow the instructions. I had one for my '98 Mustang and it was a great source of info. Myself, I would like to check it out before hand to make sure that they will have the engine specs for the Bullitt before I get one since the specs for the Bullitt are going to be a little different than a regular GT.
