Mark - Sorry about the mix up on the part number.  The bit I was talking 
about is just like a square drive bit, but with 3 sides.  My set is in a 
red rubber type case just like the one for 93388, but was purchased a 
few years ago.  The easiest thing might be hitting a cheap screwdriver 
with a bench grinder to make your own since a bit isn't long enough even 
if you had one.
