6.There are two other subheadings that you can utilize through the main screen pulldown menus. Under the information menu you will find Casting Numbers and Mustang Clubs, as well as the previously mentioned four sub-headings. The Casting Numbers screen, shown here, will give you a casting number, Ford part number, and basic description, along with fitment and notes, such as number of fan blades, diameter, length, etc. for most external engine parts. If you're not sure if that fan blade is for an air conditioned car with California emissions, this screen will tell you. The Mustang Club screen gives a complete listing by state of all Mustang clubs and their addresses.
