Anyone have their windshield out? Windshield trim clip Q

My Scamp is at the the glass shop getting the windshield installed. Before they can put in the glass they need to install the chrome trim clips and they've hit a snag. There are 23 clips (4 one size, 19 of another size) and they're not sure where the 4 larger size clips go. I suspect they might go along the bottom to hold the lower windhield chrome trim on. Does anyone know where these 4 larger clips go? The glass shop is saying I need to buy more clips (4 smaller ones) before they can put the windshield in but why would there be 4 large clips in the kit in the first place (surely it's for a reason??)??
