Swing-arm bearing kit..
Hi, madpugs...
I just take bearings and seals to a local bearing supplier. Most are stamped with the manufacturers name, some have the spec number stamped on the edge. The parts manual for your year may have the bearings identified with manufacturers number, and a good bearing house can work over the phone with you to identify the sizing. The "Owners Doc!" on the left sidebar may have the info for the replacements in the parts page.
