PS If you don't have one you must get a Mid Fifty catalog! www.midfifty.com In addition to listing about every part available for the 53-56 F100s and up, stock and/or modified, it has excellent useful exploded assembly drawings, and much additional handy information in it, and the best part is the call and the catalog is FREE! All the gals at MF (It's an all female owned and operated business which I'm sure your wife will like to hear) are all the most knowledgeable, helpful and friendly in the business. They know and understand what customer service is all about. They even include tootsie rolls in each order!
