The only advice I can give you is from my years of being a mechanic. Just about all bearings have multiple uses and are Ethier identified by the numbers on it or by directly measuring. In my area we have a company that only deals in bearings called EB Atmus and they have always had anything I have worked on from cars and motorcycles to lawn equipment and even a washing machine I fixed once. If you are near a metropolitan area there will be a similar business there. The price is always much cheaper because you are cutting out the middle man. If after removing you are not proficient with a mic. they will gladly measure it for you. I have brought in bearings that had to be brutalized for removal in pieces that they were able to get measurements from and set me up. This is the only way I have been buying bearings for years.
