Ultimate Mustang
by Patrick Covert et al; DK Publishing; 2001; ISBN 0789462443
This book contains information on the 1992-93 special editions on page 149. I have not seen this book but, from what I have been told, the information is not really correct and that the picture is not too good. Otherwise, I hear the book is generally OK in its coverage of the Mustang. From looking at the except on amazon.com, it looks like the contents of the book are very "visually" appealing. Thanks to Bill for providing this information.
