I would of though they'd be standard, but you never know. Mines under the window and just right of center as you look at the boot. Maybe its been taken out or fallen off.
*edit* if your after a new one, try asking in the for sale section, or a stealers. Cant see it being too much. Saying that, it cost me £2 for a bleed screw for the radiator.
