I'm installing the C&L Plenum and I can't get the last two screws in they are the screws by the driver's side that connect the round top piece I wish I had a digital camera. I can't get them in I had to cut them and they just won't screw in. I can only get 1/4 of it in should i cut it again? They seem to be going on an angle. I m ready to smash it up Help
