All this Ys talk is nice and all but....

I really need to know what size the screws are that hold the casing of 
the Turbo Duo together are. Mine has no screws whatsoever, and I would 
REALLY like to remedy this situation. Should I just carry my Duo into 
Home Depot, or what? 
Oh, Ys rocks. I should be picking up VI this week. Can't Wait!
