To find out if a hub/rotor kit like Kodiak # K2HR958QD11 will fit on an existing axle/spindle setup you need to know what bearings are required for the spindle. This 10K disc brake kit uses inner bearing # 28580 and outer bearing # 25580 and these bearings fit on a number 99 spindle. An article on popular bearings is linked.

To know what bearings fit your spindles you will need to either have the original bearing numbers or measure the spindles very precisely using a digital caliper. Please refer to the linked diagram that shows you where to measure the spindles with a caliper like # PTW80157.
