i like the ball bearings for the carrier. tapered roller bearings are the best if you can find a manufacturer that makes a carrier for them. roller bearings are fine for pivot points but they usually generate more heat when spun fast vs a ball bearing. did you try atk for the washers? maz might have some also. don't count out haydug either.
had a talk with a local bearing supply house. Ball bearings are the way to go to replace in stock carriers. I got OEM Fafnir bearings coming and seals. Are the Dales the only ones that use the washers ?? I dont remember seeing them in our EX or R.
