Should be "10144117A" but if you really want to confirm check your service manual book and look at the vehicle information label stamped. If you find the codes 1KZ or 1KY on there that indicates the type of rear brakes you have fitted from the factory and you can cross match the codes on the ECP/Brembo Parts site.
Also when you receive the pads make sure they are the ones specified as I find that ECP have the odd habit of bringing the wrong ones out. With Brembo the box part number is P 85 073 for the 1KZ/1KY rear pads.
