Repair Plate Rules:
8 total 6x6x1/8” plates
Plates must be 1-inch apart including the weld; 1⁄2” weld max. They cannot touch or be attached to the driveline components at all. Must be welded on the frame rail only.
If you are over on plates you will remove completely
Frame Bumper:
Bumpers Brackets - 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 bracket that is 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), on one side of the frame. 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 1⁄2” bolt or less, and it must be done vertically. All brackets must touch the bumper and cannot be cut apart to lengthened. No part of the bumper bracket may extend back further than 14” from the front edge of the frame rail
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 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.
Bumpers –
Stock Bumper - You may reinforce bumpers on the inside of the bumper all material must be
inside the factory front and rear bumper skins with no alterations. You may trim bumper ends or fold them around. Welding the bumper skins (chrome to inner liner) is allowed.
Manufactured Bumper - If you choose to manufacture a homemade bumper it must conform to the following size limits. The bumper may be built up to have a 15” point from the farthest point from the back side of the bumper to the point, however the point itself may be no more than a factory Chrysler pointy itself and spanning over a 36” span across the bumper. They may be 8” tall.
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 whichever is lower. Bumpers must be in stock location and must be mounted in the same location the factory mounted the bumper. 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.
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.
Rear Bumper Brackets must follow the front bracket rule, no longer than 14” on the frame. The rear bumper bracket only, may also be on three sides of the frame on the back 4”. Wagons do not weld the bumpers to the body or move the bumper to the back frame rails.
Frame Shortening and Tilting:
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 minimum from the front a arm mount hole to the front edge of the frame and frame must be cut square. *80s and newer cars are allowed to cold bend in one location in the side rails only or cut factory seems apart to bend their cars down as long as no more than the 12” of weld (referred to in next rule) is used to. Do not abuse this rule or you will cut. Your frame must stay in factory shape when tilting.
Frame Welding
You can weld top and bottom factory seams from the most forward part of the upper a-arm. You are allowed a total of 12” of weld behind the a-arms and the weld must be marked with fluorescent green paint. If you extend past the 12” you will cut daylight out of the frame seam to get it back to 12”. If any welds are ground down to hide you will remove that frame section piece.
All welds on the car should not be any wider or taller than 1⁄2” max.
Rust Repair – Frame - If your frame is rusted through, call for instructions on how to the fix the rust hole. DO NOT FIX IT WITHOUT CALLING AND EXPECT US TO ALLOW YOU TO RUN IT. NO RESTUBBING OF ANY FRAMES, NO EXCEPTIONS. IF YOU HAVE A BENT FRAME, FIND A NEW ONE. YOU CAN NOT RESTUB IT.
Frame Shaping – NO frame shaping is allowed.
You may not relocate any brackets on the frame. This mainly pertains to 1972 and older Cadillacs relocating torsion bar brackets to cut frame shorter, all brackets on all cars must stay stock with no alterations.
Front Suspension:

Only stock size car replacement ball joints and tie rod ends are allowed; no pickup or van tie rod ends. If using a weld in ring for ball joint it can not be any bigger than 2 1/2” tall by 3” in diameter, do not weld to the frame only the a-arm
A-Arms - A-arms may be welded but may not be reinforced. If welded, it may only use up to 2- 2x4x1/8” thick strap per a arm, these straps are the only way your a-arms can be welded down. 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. All a-arms must bolt through the factory holes like they came factory on that car. 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.

You can change coil springs to a stiffer spring, you can double the rear springs (they may be tied together in no more than two spots, do not weld them together), do not put spacers in sagging coil springs to get your height, do not raise the suspension any other ways except what is listed above. You can wire, or chain coil springs to rear-end and frame to prevent springs from falling out, do not go through body as this would be another body mount.
You can loop chain or wire (1 loop of 3/8” chain or 4 loops of #9 wire) from rear end to frame in 1 spot on each side, must go around frame, do not bolt the chain to the frame. We are going to allow you to weld the chain to the side of the frame, for your chains from the frame to the rear end, you can weld one link only to the side of the frame if you choose to weld the chain instead of wrapping it around the frame. This is a standard chain link
Or you may use 2- 1” all thread going from your rear end through the package tray to hold your rear end in. You are allowed a 4x4 washer on top of package tray. This may not go through the body.
