mains are:12207-42L10 through 14 depending on thickness for the regular bearings

12261-42L00 through 04 depending on thickness for the thrust bearing

rods are:12111-58S00 though 02 depending on thickness (grades 0-2) respectively. if you want odd size bearings they are different p/n's

nothing cross references with the US

sileighty89- did you find anyone that had the bearings? Because I ordered L series bearings but they were the wrong parts.The Dimensions are exactly the same but the tangs for the bearings are in the wrong spot and the Thrust bearing is too wide.So right now im looking for Main bearings (black) and Rod Bearings (Neutral)

Shoot me a e-mail if you find anythingThanks Brian
