12. Four cylinder cars should remove the front plastic part of the bumper.

Bumpers can be welded to the car, but there should be no metal added other than small nuts and bolts. This is at the judge's discretion. There may not be any steel in the bumper area. This means no flat, channel, square, U-shaped, or any other shaped steel. If the bumper needs to be repositioned it may be done using the minimal amount of welding and using eight inches of 3/8's threaded rod on each frame rail, one per side, no exceptions.

You will be able to use small diameter threaded rod, no bigger than 3/4", to anchor the bumper to the frame. No truck bumpers are allowed on the front or rear of the car. Any modification to the brackets needs to look professional or it will not be accepted. Wrecked cars only will be able to lay a 2" long by 1/2" wide bead of weld to reconnect the bumper to the frame, no metal will be allowed in this area. Anything else done other than that stated above, will not be allowed.

The reinforcing of the front suspension on the 78 and newer GM cars is allowed only to equal the Chrysler front suspension. Position one bolt on one side of each A arm, welding or bolting is allowed.

There will be not clamping the frame rails with strips of metal that sandwiches the body and frame together. All trailer hitches must be removed from all cars. There will be nothing allowed to hold the sub frame up in any car. This means no bolts, steel plates, wire, cable, and/or strapping. We ask that you remove all this stuff before entering the fair. There are no excuses for rusty or pre-run cars.

We will allow Three 5/8 size bolts throughout the inside of the car. You will not be able to change sub frames from other cars, stock only.

The car numbers will be placed on both doors and the roof. There will be no metal added to the car's body on the inside or underneath. We will allow the outside seems (doors, hood, and trunk) to be welded. The cars with the fans sticking out of the hood will not be able to race due to safety reasons. Any body modifications will be allowed as long as there is no metal added or welded to the cars body (ex: crushing back of car to change appearance). There will be no added metal to the floor or any other part of the car. If there is a hole, use galvanized or aluminum sheet metal.

The original gas tank must be removed from the rear of the car before it enters the fair grounds. Entering the fair grounds with the original gas tank still attached results in disqualification.

The use of floor shifters is allowed. A working seat belt is required. The belt must be secured to the body of the car by a bolt positioned under the driver seat. Safety belt positioning is strictly enforced!

The use of transmission coolers will be allowed. However, they need to be in the back and covered with steel. Any fuel, oil, or transmission lines that are not safe, will be rejected. These safety precautions are strictly enforced!
