Where are the screws to the stock intake box on the 03 Monte carlo LS?

Thanks to all of you who replied to my post about removing the stock air intake. where exactly are the screws. do you have to remove the actual filter first to get to the screws? where are they is what i should  really ask?

I just put my FWI on last night.  There were 2 bolts at the top of the box to pull it apart to pull out the computer then the rest of the box is basically just snapped to the lower fenderwell.  Just pull up on it and it should snap out.  There wasn't any bolts inside at all.
