looking for .009 undersized bearings - or modify my .010

Long story short, I bought a reman'd crank that came with "matching" .010 undersized bearings, so I didn't bother to plastigage them when I put it in. Mental note - ALWAYS personally double check EVERY machine work you have done on ANYTHING. After thinking through the list of symptoms, I decided to pop off a rod cap and check the clearance. The plastigage was squished to literally twice the thickness of the .001 strip, so I'm guessing actual clearance is somewhere around .0005. The specs call for at least .0015, so I'm at least .001 too tight on the rod I checked. If I'm lucky, I just got a set of bearings that were out of tolerance somehow. I'll be measuring the crank with micrometers and comparing that to the original specs tonight to see where I'm at. If the crank turns out to be only .009 smaller than original instead of .010, is there a relatively easy DIY way to get my clearance within the specified range? Something like a .009 undersized bearing instead of the .010 that came with it should work nicely I would think, but I can't find anything of that nature.
