Brass speaker spikes

I ordered brass speaker spikes for my speakers from Brass & Granite Audio (Oregon). The parcel was sent via USPS on 23 May 2008 but never arrived. According to our postal authorities, the parcel never crossed the US border, otherwise it would have been registered as "exported". The sender has proved to be an honest person and refunded my money, but I don't have any spikes and the speakers (Italian Nightingale CTR-2) are standing on the carpeted floor. The stock spikes provided by the manufacturer are too short to pierce the carpeted floor. Does anyone know a reputable online vendor to order spikes from?

Thanks in advance!
