1992 Audi 80 ABT Heater Bleed Hose
 

Evening,all,
Before I order anything from Eastern Europe, has anyone got one of the following lying around in their garage:

893819375F 1992 Audi 2.0 8C B4 (ABT engine) heater return hose with a bleed screw. The part number was taken from 7 Zap and does specify that it's for a right-hand drive vehicle.
Failing that, any successful fixes for a leaking bleeder using M10 screws? Or will an Audi A4 WHT 000316 plastic bleed screw fit?
Vorsprung Durch Technik didn't really apply with that particular design. :-(
