How do I loosen the damn bmw clamp? its nearly impossible with the amount of space Nevermind about this one, I just spent some extra time to pry the shit out of it.

Also, what do I do with the crescent wrench on the end with the metal and plastic? I havent read anywhere on how I am supposed to loosen that?

Do I hold the plastic part so it stays and doesnt move, then press the entire thing in?

Someone who has done this please help me, I dont want to break anything
