Allen,
I think the studs themselves come as part of the S3 from the factory, or at least they look like they do /ubbthreads/images/graemlins/confused.gif
I just went on down to the hardware store and got some stainless bolts and washers, sorry, but I can't remember what size, but there have been a few posts about this, so try searching for it. IIRC it was John (Robins) who posted the right size bolt.
