Need a little help

I'm going to switch the shafts in my TM SLDRs from KBS C-Taper 90 shafts to Nippon Modus NS Pro. I have everything prepped and ready to go. But here's the problem.

The new shafts are 0.335 and the old ones are 0.350. It's only a small difference but the head slightly rattles round in the hosel. The epoxy I'm sure will take care of that, but I want them to fit snugly in.

So I need shims but don't have any and it will take weeks to order them in. I was planning on making my own by cutting...
