may want to check and see which you need. I belive there are two different versions. One version where the chassis extends out to the bumper, thus you would only need two brackets that extend diagonally. My 72 uses this type.
the other version is for frams that are cut, from factory, just behind the rear body mounts. This requres 4 brackets, 2 that extend out to the bumper from the chassis, the other 2 extend out diagonally. My 71 uses this type.
but i guess you already know since you mentioned that you needed 4 pieces. /forums/images/graemlins/peace.gif
