FRONT NOSE:
 

1. ​In the event that the lower part of the nose has been worn off, a replacement wear strip may be installed on the nose. This part will be made from plastic only, and must measure a maximum of 1-7/8 inches tall (photo N1). The valance piece must be mounted in the same plane as the original air dam and will be subject to tech approval.
    

2.  The nose is manufactured with a finished wheel opening and must not be altered in any way (photo N2).

4. The maximum front overhang from the centerline of the spindle to the leading edge of the lower air dam at the centerline is 47 inches (photo N3 and photo N4).
    

5. The maximum distance from the bumper line to the leading edge of the air dam is 4-1/2 inches including the wear strip. This dimension will be regulated by the Nose Centerline template (photo N5).
    

6. The nose must fit the Nose Centerline and Fender templates within the allowable tolerances (photo N6).
    

7. The maximum width of the nose at the wheel opening will be 79-1/2 inches. This dimension can be checked with the Nose Side-to-Side template (photo N7).

​

FENDERS:
 

1. Only approved fiberglass or molded plastic fenders produced by approved manufacturers containing visible labels will be allowed for competition.
    

2. The only alterations allowed to be made will be trimming excess material from the trailing edge of the fender at the fender/door intersection to allow for wheelbase variations.
    

3. All fenders must be flange fitted to the nose.
    

4. Wheel openings may not be larger than 7 inches from the edge of the wheel (not the tire) on the front & rear of the wheel opening (photo F1). Altering the wheel openings is prohibited.
    

5. The left fender must fit the Left Fender/Nose template (photo F2) and the right fender must fit the Right Fender/Nose template (photo F4) within the allowable tolerances.

3. Roof rails will not be permitted.
    

4. The roof height is measured 10 inches back from the windshield/roof intersection on the centerline. The height will be 47 inches minimum. This dimension coincides with the minimum rear door height of 33 inches and the minimum deck lid height of 34-1/4 inches. If these dimensions are higher, the roof height must increase by the same amount. This height will be checked using the “Referee” (photo R1).
    

5. The air intake opening must be 2-1/2 inches x 20 inches plus or minus 1/16 inch (photo R2 & photo R3). This will be regulated by the Air Intake template (photo R4).
    

6. Quarter panel window areas must be cut out to scribe line and have polycarbonate windows in both the left & right sides.
    

7. The shape of the roof is regulated with the Body Centerline template (photo H3), the Roof Rear Side-to-Side template (photo R6), & the Roof Front Side-to-Side template (photo R8).
    

8. The correct location for the Body Centerline template (photo H3) is 2-3/4 inches to the right of the hashmarks at the front and rear of the roof. From the roof, the template extends down to the hood at the front and between the spoiler halves at the rear. The hashmarks are located above the windshield and above the rear window.
    

9. The Roof Rear Side-to-Side template (photo R6) is located at the top corners of the rear window at a 90° angle to the roof (photo R8). It extends down the quarter panel across the quarter window, over the top of the quarter panel, and down to the wheel opening.
    

10. The Roof Front Side-to-Side template (photo R8) is located at the top corners of the windshield and extends down to the top of the doors and part way down the side of the door. The proper placement of this template is at a 90° angle to the roof (photo R7) and 20 inches back from the trailing edge of the "A" post where it meets the door.

​

DOORS:

2. All quarter panels now are manufactured with a finished rear edge that fits into the recess of the bumper cover. No trimming required as in the original ABC quarter panels.
    

3. The quarter panels must fit the Roof Rear Side-to-Side template within the allowable tolerances (photo Q2).
    

4. The height at the quarter panel/deck lid/bumper cover intersection will be 34-1/2 inches (34-1/4 inches minimum) on both the left and right sides (photo Q3).
    

5. The quarter panels must be mounted at the same plane as the deck lid & the top of the bumper cover as shown (photo Q4).
    

6. The Rear Deck template works with the Body Centerline template (photo Q5) to maintain the proper shape of the decklid and the shape of the top of the quarter panels. It is approximately 2" forward of the decklid hold-down recess (photo Q5).
    

7. The Rear Deck template (photo Q5) has been added from the original builder's template and enhanced to go down the sides of the quarter panels behind the wheel to control the original intended shape of the quarter panel and will also
   control the front edge of the quarter panel behind the wheel opening to be 2" inward from the outside of the sidewall of the tire on both sides.
    

8. The quarter panel (in front of wheel) must be perpendicular to the ground for the first 15 inches. The maximum gap is 3/8 inch for the first 15 inches up from ground (photo FDQ1 & photo FDQ2). The measurement will be taken from the leg of the
   quarter panel to the framing square as indicated with the arrow.

​

WINDOW DISCLAIMER:
 

1. All polycarbonate windows must not be installed using rivets as it is likely to shorten the lifespan of the window.

3. The windshield braces must be mounted in the recesses provided in the window bed.

​

REAR WINDOW:
 

1. A clear, molded polycarbonate rear window with a minimum thickness of .093 inch must be used in all cars. The same shape rear window will be used for all body styles. Flat, unmolded rear windows are not allowed.
