Helm is the supplier of Ford's factory manual, but as stated previously, you can find them on eBay all the time and for a lot less money. I have complete sets of factory manuals for all four of my cars and there is NO comparison between them and the Haynes and Chilton's crap they have at the auto parts stores. Make sure you get the EVTM book as well as the service manual for your car. It offers highly detailed informaion on the electrical and vacuum systems for your car. Invaluable.

 

The best number to call is (800) 367-3788, 8a-5p EST. This number will get you to the tech dept in the warehouse.
