The judging sheets are broken into 5 main categories, Interior, Exterior, Trunk, Engine Compartment and Undercarriage. At the end of each of these categories is a 5 point item for other items not proper or original, including over-use of Ford accessories. The purpose of this section is the keep owners honest and not go out and build a car that Ford possibly never would have sold new... for example: attaching all K code engine components to a '66 C code.
1 or 2 accessories here and there are ok, but just keep them tasteful and "believable".
