Based on the seal measurement, it sounds as if the best fit is going to be the Bearing Kit, 15123/25580 Bearings,10-10 Seal, # BK3-110. The seal that is included in this bearing kit measures 2.125 (2-1/8) inches. The inner and outer bearing numbers remain the same as the BK3-100 kit you have referenced.

You want to be certain to get the correct kit to avoid potential problems down the road. I recommend taking a look at the other set of bearings/seals on the other hub to double check, if at all possible.
