where do the hood bumpres go on a 72 challenger?

the hood on my wifes 72 challenger shakes going down the road so I ordered a new hood bumper kit, the wedges towards the rear and the front hood adj bolt rubbers were a no brainer but I have 4 round bumbers left, all look like they go in a small round hole-1/4" or less. I have been looking at pics and it looks like 2 may go at the rear of the hood, on the hood, and one pic looked like it had a single one in the center rear of the hood? any help would be appreciated, thanks guys!
