how the hell

i just got my new grille and bumper 2day i cant figure out how to get the bumper off. i see where all the little pain in the ass bolts go but i cant get to them. i thought it might be easier to take the whole thing off, bumper, corner pieces and tha valance, but since its me, its not easy, i pull on it and i can feel where its still botled on but i cant see shit, someone please hurry and help me...yes i posted it twice, once in here and in exterior

2 bolts in the front . Then open the hood and there are 2 bolts were the frame is. Should be 17mm.

that will pull the whole bumper and brackets out then switch the bumper whiel the brackets are off and bolt it all back up again....
