Long shot: Toledo brake bleed screw

[hugh_]

I was bleeding the brakes on my 2004 Toledo this afternoon and in the process of loosening the bleed screw from the NSR caliper I've managed to strip it (just the bleed screw thread). Does anyone have a spare (or a spare caliper from which one could be borrowed)?

I'm in Kent and can collect, but need the car tomorrow so its a bit urgent!
