I know the manual says replace the bolts every time but I have had no issue with re-using them. They aren't torque stretched like head bolts or anything.
I've also never had any visible wear on the washers. If you still want them, I have a used set, let me check if they're complete.
Or you can get them new. Heres the hardware with no bolts:

I know for a fact that EBR still stocks the whole standard set as well as the racing rotor solid mounting kit (IMO I highly recommend that). It will probably say 'backordered' but don't fret, order them anyway and they'll put a set together for ya.
