72 Demon front windshield reveal clip install

Just opened a set of clips and screws I got for the front windshield. There are 17 of one clip and 5 of another one? The 5 appear to have a slightly elongated hole where the fastener screw goes through and all the others have a perfectly round hole for the screw. However my Demon has 8 holes drilled across the bottom so they can't go there. Does antbody know the placement of these clips. Thanks....
