found this on a site i was looking at...joe

At least some of the 75-80 Ford Granadas, Mercury Monarchs, Lincoln Versailles and 71-73 Mustangs and Cougars (what about
Torinos and Montegos?) have the larger 11 inch diameter discs. The Granada/Monarch/Versailles cars are the most popular
donors for this swap because they have the larger rotors, are relatively common (and therefore inexpensive) in junkyards, and
have parts that are still stocked by local auto parts stores. Also, if you are hunting front brake parts from a Granada, Monarch, or
Versailles, check the rear for disc brakes. Some Granadas and Monarchs, and all Versailles came with disc brake equipped 9"
rear ends.
