I'm not familiar with a rebuild kit. From what I've seen most people try to avoid having to mess with the actual gears by doing what I'm doing, or give them to a good gear shop for proper setup if you must change the r&p gears. Other than that you pretty much need to use the ASA and find OEM part numbers for seals and bearings etc.
