So I'm swapping the engine from my Forester to my 01 2.5RS to get her running again and I ran into one issue. The trans on the Forester has a type of sleeve over the input shaft where the throwout bearing sits but the 2.5RS does not(the input shaft is also marred up a bit) and so the bearing doesn't fit correctly and can move around a lot. I've tried researching for that part but came up with nothing. What part is it? Can I swap it? Ideas?
