I need to know where I can purchase some replacement bolts that came
out of my SSR (Speed Star Racing) 19 inch GT3 Wheels.  SSR is a
Japanese company.  I can't contact them and the U.S. distributor
(Tirerack) can't help.

The bolts are metric (6mm, I believe) with a cap head.  The shank is a
little more than 1-1/4 inch long and only threaded for half it's
length.  The top edge is chamfered.  The tricky part is the internal
12 pt socket head which seems to fit a Torx-40 bit (but may be
something called a "triple square").  Pretty sure they're stainless
steel - may be plated.

To make this easier, I have good pictures of one of the damaged bolts
next to a scale that I can forward.
