I have a guy who is seeking to join my local Mustang club who says his recently purchased '66 coupe is a former drag car. He wants to restore it and is searching for info. He mentioned that the team included two coupes and one fastback, all small block cars with four speeds and nine inch axles. He bought the car recently from a buddy in S.C. and wants to restore it to its racing glory days condition. Thanks for your attention.
