we just chopped the brackets into 4 pieces. Pretty much just cut the middle of the bracket off . Did the trick.

As for the overflow tank, the thing that it slides on to. We just removed the bottom bolt and loosened the top bolt. Rotated the piece, and tightened the top bolt. And slid it back on, fit great. If you want you can use a self tapping screw and put a screw on the bottom but it isn't worth it.
