1999 Legacy B4 RSK twin turbo manual - clutch issues

Hi, I have a 99 Legacy B4 RSK twin turbo manual which recently popped the clutch, The problem is when the mechanic removed the Thrust bearing from the pressure plate he broke the circlip ring that retents/holds it together, now I am struggling to find that circlip ring since I have no idea of its size or better yet how it looks like....Pls assist, Frustrated Scooby driver:runaround:
