Need part # power supply to lcd cable

My Mac is an iMac model #A1225 (24" aluminum body). I need the part number for the cable that runs from the power supply to the LCD monitor. I've looked online for it but haven't been able to find an exact match. Also, if anyone can suggest the best place to buy it, that will be appreciated as well.
