Instead of using bumper brackets you are allowed to use 1- 4” wide x 3/8” thick strap extending from your bumper down one side of the frame and cannot extend any further back than the very front most part of your top-front a-arm bracket factory weld. The portion of this 3/8” strap welded to the frame will be measured against the 48”inches of  ¼”strap allowed for frame repair. 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.
