All you have to do then is to carry out an internet search using your favorite search engine. You can be specific, by naming the actual part, or simply carry out a general search for Mustang parts. The site you choose will then lead you to the part you want by means of menus. You might be asked simply for the model and year, or for the V.I.N. number or something even more specific, such as the transmission reference as detailed above. Whatever method is used, you should be able to locate and order the part you want.
