Frame:

Bumpers:
Bumpers are interchangeable. Any automotive bumper may be used on any car, but no more than one set of bumper brackets may be used. Bumper brackets may be from any car that is legal to run in your class and on only one side of the frame. Bumper brackets must be one of the two following methods. First way – factory bumper brackets that are legal to a car in your class may not extend any further back than the first 14” of the frame. You can weld bumper brackets to the frame (single pass only). The bumper may be built to have a 14″ point from the farthest pony back from the back side of the bumper to the point. However the point itself may be no more than factory Chrysler pointy itself and spanning over 36″ span across the bumper. (Will have a cut out template to follow). They may be 8″ tall unless loading an unaltered factory skin. Replica bumpers are allowed. You can weld bumper brackets and shocks to the bumper. You can weld shocks to shock brackets. You can collapse shocks, and you can bolt the shocks to the towers with ½” bolt or less, and it must be done vertically. All brackets must touch the bumper and cannot be cut apart to lengthen. OR Second way – INSTEAD of using bumper brackets you are allowed to use ONE 4” wide x 3/8” thick plate extending from your bumper down either a side, or the top, or bottom of the frame choose only one cannot wrap a corner with it and cannot be any longer 14”. You are also allowed to wrap this strap around the front of the frame 4” to create an “L” shape. This is to give you enough material to weld your bumper to the strap. Plate may be reconfigured but must stay only 4” wide max. Do not bend the plate past 90 degrees when you reconfigure the plate. Plate may be welded on either side of the frame or
the top or bottom, your choice. Do not abuse this rule YOU WILL CUT. You may reinforce bumpers on the inside of the bumper. You may trim bumper ends or fold them around. Welding the bumper skins (chrome to inner liner) is allowed. Weld them solid, we do not want them coming off. Bumper height not to exceed 22” to the bottom of the bumper to the ground and must be a minimum of 14” from the ground to the bottom of the bumper or frame. Bumpers must be in stock location. The bumper must be completely in front of the frame rails. No part of the bumper may extend back past the front most part of the frame rails 3 Front and rear bumpers may have 4 loops of wire from radiator support/trunk lid or deck (to sheet metal only do not go around core support bolts) to bumper (not frame). These cannot be placed in front of the radiator. The bumper may be built up to have a 14” point from the farthest point from the back side of the bumper to the point over a 36” span and 8” tall. Rear Bumper Brackets must follow the front bracket rule, no longer than 14” on the frame. Wagons do not weld the bumpers to the body. Rear Bumper: The only way you can weld bumper to frame is if it came from factory with brackets to the frame. Brackets must follow the front bracket rule, no more than 14” on the frame. If the brackets are mounted to the body they have to stay to the body. Bumper has to stay with those brackets. Do not move the bumper to the frame. You may weld brackets to the body. Bumper can weld to brackets and the body. Bumper welding to body is 5” on 5” off etc, you can use 3” x 5” x 1/8” strap to weld bumper to body.

Frame Shortening:
You may shorten the front frame on a FoMoCo or GM on the front frame only. You may cut the frame off flush with the front edge of the body mount hole. If it is a weld on mount leave the remaining portion of the body mount in place. If you remove the body mount completely or relocate it you will not run. 76 and older Cadillacs must measure 18 inches from the back of the bumper to the front of the spring pocket. Frame Welding: A total of 14” of welding allowed behind the a-arms. All welds must be marked with orange paint. This will allow the FoMo Cars to cut and tip the box and reweld with 14” of weld and the old iron cars to reweld the seams where the factory missed or any other factory welded seam. Do not weld the front frame or box to the side rail. Only factory welded seams may be rewelded. If you choose to cold bend the car do not support the cross member. These are the only ways to bend a fresh car.

Rust Repair – Call before fixing any rust on the frame.
Frame Shaping – NO frame shaping is allowed.

Front Suspension:
Tie Rods and Ball Joints – Aftermarket tie rods allowed (no “Big Chiefs”) with stock size ball joints. Do not re-engineer the way the steering components mount to the frame. Only stock size car replacement ball joints and tie rod ends are allowed, no pickup or van tie rod ends. A-Arms -A-arms may be welded or bolted down with up to a 5/8” bolt but may not be reinforced. If welded, it may only use up to (2)- 2”x4”x1/8” thick strap per a arm. This strap must weld to the a-frame and cannot extend farther forward or backward than 1” past the widest part of the a-frame. No changing or modifying the a-arm brackets. COIL SPRINGS must be a factory car coil spring for a car that is permitted to run in this class. Steering box – May be interchanged but must remain a stock box for a car that is legal in the class you are running. Pitman arms must remain stock or stock replacement Idler Arm – Idler arm must remain stock or interchanged for an idler arm for that is off a car that is legal in the class you are running.

Homemade clamps can’t exceed 2x4x1/4”. Eyelets must be in the factory location of the car you are running. 2” arch one direction from center of eyelet to eyelet. You can change coil springs to a stiffer spring to get your height, do not raise the suspension any other way. You can bolt, wire, or chain coil springs to the rear-end and frame to prevent springs from falling out, do not go through the body as this would be another body mount. You may weld leaf spring mounting brackets to prevent them from becoming unbolted (single bead no wider than ½”). You can loop chain or wire (1 loop of 3/8” chain or 4 loops of #9 wires) from rear end to frame in 1 spot on each side, must go around the frame, do not bolt the chain to the frame.

You must leave at least a ¾ space if using the factory rubber spacer. Do not devise a way that enables you to suck them down tight. Radiator support mounts can be removed, and you can suck the radiator support down solid. Absolutely no body mounts may be moved or added, do not shorten the front of your car and move back past the body
mount hole as your car will not run. If you have to build core support spacers you may no weld it to the body or the frame mount. Core Support Spacers cannot exceed 3” square material. The front frame must not be shortened so that the 1” all thread must pass through the factory stamped hole. The all thread may only be welded to the side of the frame in this location.
