SS caliper bolts?

[carbold]

Posted this on the vendors forum but it's not having much feedback...
Does anybody know where I can get those bolts in SS?

Can't find anything with a 5 cm long shoulder...
Even something longer would be fine as I could cut them to the length I need.

Please avoid the usual "I wouldn't do such a dangerous thing bla bla bla"

I've fitted stainless fasteners to my 1100GS calipers,I think I got them from Motobins.
