That's common, most kits contain both large and small pattern shims.
I might have a set of small ones stashed somewhere that I won't need, let me look around this weekend.
I usually order an extra set of shims every time I rebuild my knuckles, tomorrow when I get back from skiing I'll try to dig up my measurements from my last rebuild. I'm thinking one set is usually not quite enough on mine. Every cruiser is different.
