Rear CV Assembly - Lost Ball Bearing :(

[ninjanick]

So I thought I put all the ball bearings in a bag, but after re-assembling the rear driveshafts, I noticed I'm short one ball bearing. Question is, does anyone know the part for one of these? I looked at opposedforces.com and could not find the part number for this. I'm I just out of luck?

I don't think its a Subaru P/N, just mic up another one and try and order a ball bearing of that diameter.
