What I call a flip bracket is the U-shaped bracket that comes in a flip kit for a Chebbie. It goes under the perches & locates the rearend to the springs by fitting up inside the recess on the bottom of the original perch. It takes a little grinding here & there but will work if you don't have a welder. On all my flips I use a lower shock bracket from either a C or B body, whichever I can find
