Clutch Slave bleeder

Does anyone know where to source a bleeder screw for a clutch slave cyl on a b5 or b5.5? or have one kicking around? Doing a swap and I am missing a bleeder screw on the slave. Everywhere I looked says you need to buy a new slave.
Thanks

Check here for a metal one: http://www.gruvenparts.com/audi-a4-a6-vw-passat-b5-stainless-slave-cylinder-bleeder-screws/

The local dealer doesn't sell it?
