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 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). 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

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.

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. 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.

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 body only they have to stay to the body. Bumper has to stay with those brackets. Do not move bumper to the frame. You may weld brackets to body.

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.

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 with the cross member. These are the only ways to bend a fresh car.
