Have you considered a Speedi-sleeve?  You may have to look it up by size if they don't have that particular application listed.  I've had good luck using a sleeve that was listed for a shaft some .010" larger than the one I had; used some Loctite "circular parts mount" under it and it sealed fine.

Something else to look at is how snugly the shaft fits into the bore that supports it.  On my Chevy, that bore was plain cast iron, and it wore oversize, allowing the equivalent piece (the Chevy didn't use a flange, just a CV joint) to wobble around.
