You need to measure your crank journals. THEN you either get the crank turned down to the next available size - and get the corresponding bearing size. OR if you're still in spec and the mains are in good shape, you CAN get the stock size bearings. Notice I am capitalizing words here so you understand this isn't just a cut and dry thing, especially if you want this to be a permanent or ideal fix.
IDEALLY, you get the crank turned, and the machine shop will tell you which bearings to get, or give them to you as part of the package. That's been my experience.
