Go with a shim as Pre 68 Dave does. If you are not comfortable making one, find a mechanic that does rear axle work. They usually save old shims left over from gear or bearing replacements. At least I do. I have about 20 to 30 different sizes, and hundreds on hand. It's also a lot easier to crush down .010 than .080 to .100 on a new sleeve, to get the correct bearing preload.
