That PITA bracket is held captive by 2 Allen head bolts that go through the oil pan and two 10 mm nuts. Both Allen heads must be removed. The 17 mm nut is removed from the bottom with a socket and ratchet on a short extension. Good that you will be eliminating that stupid contraption with your kit. I may make a custom hose to eliminate mine.
