That does not mean your size will be the same. 9 balls in each side for the rear, ten balls each side front. You can buy new loose ball bearings cheap, no need to reuse old questionable ones. I bought bags of 100 each size for about $2 each. Or go to your LBS and pay about ten cents or less per ball. If you don't have a micrometer, you can buy a cheap one at Harbor Freight for $2 which works fine, or move up to a digital unit for about $20. I just bought an 8 inch digital unit on sale at HF for $20. But the plastic $2 one is fine too (I have one of those also).

If you have caged bearings, take them to your LBS and get new ones.
