There are two different bearing kits that could work for you.

If you need a seal with a 2-1/8 inch inner diameter you would need the part # BK3-210. If you need a 2-1/4 inch seal you would need the part # BK3-200.

You will need to remove the hub and measure the diameter of the spindle where the seal rides to see which kit you would need.
