Need adaptor for iMac....Firewire 6 pin to 9 pin?

No longer needed...found at B&H. Thanks.......Does anyone know where I can find a FireWire 6-Pin Female to 9 pin Male Adapter (not sure how many pins on the back of my iMac....looks like 9). I need to plug my 6 pin firewire from my Sony HD deck into the back of my iMac so I can upload some HD footage from HD tapes....Thanks..
