Some folks have had some difficulty in tracking down focus screen shims from Canon. One reason they're hard to google is that Canon refers to them as "washers". There are eleven different shims, which vary in thickness. They do not come in a set; they must be purchased individually. Luckily, they're inexpensive (~$22 USD for all). I spoke directly to a Canon parts department rep yesterday and here are the part numbers (note that these are for the 5D...I neglected to ask if they were applicable to any other body). My guess is that the part number suffix pertains to the thickness of the washer in mils (again, in my state of glee that I found these things, I didn't ask that either):
I think we should all start calling these things by the official Canon name of "washers" instead of shim as this might make searching threads in the future less confusing...

Good point, Max...I edited the title to indicate both terms.
Hi Mike,
I have seen several service manuals and part catalogues of EOS camera/lens on the web. Similar codes are used to refer to thickness in millimeters.
i.e.,
003 = 0.03 mm
005 = 0.05 mm
etc.
