In 1976, Charlie Kemp built a Mustang II racing car for the IMSA All American GT (AAGT) class. He looked at the rules carefully and decided that he could get away with taking the body panels for a Mustang II and draping them over a tube-frame racing chassis. The common method of building a racer in this class had previously been to take a production vehicle and add the tube frame reinforcement to it. Kemp's method did away with the design compromises inherent in the more common practice.
Unfortunately, the IMSA inspectors did not share his liberal interpretation of the rules and placed him in the Le Mans GTX (GT Experimental) class. Eventually he was able to modify his Cobra II racer to satisfy the IMSA inspectors.
Kemp also intended to sell production Mustang II's wearing his fiberglass body panels in cooperation with his sponsor, Dobbs Ford in Memphis Tennessee. The cars were to have performance upgrades limited to suspension improvements (a sign of the very restrictive emission regulations of the period). I have been unable to determine if any of these production cars were built, or if the body panels were available as a kit. If you have info on this subject, please e-mail me.

Note that the engine has been moved back at least a foot from the stock location and that the rear injection stacks are under the cowl panel.
Note that the driver's position is moved back to compensate for the rearward engine position.
