Wheel Bearing Size

I'm going replace my wheel bearings, yet another winter project.

The victim: 1991 single axle Mastercraft factory trailer, no brakes.

After researching this, I have not located the bearing kit size. Would like to pre-order the 2 bearing kits online.

Any help here?

1991 ProStar / 351W with 1:1 Velvet Drive

Not sure if this will help, as my trailer is a '96 single axle Mastercraft but my bearings and seals are as follows:

Spindle size OD= 1 3/8" x 1 1/16"
Inner bearing L68149, inner race L68110 (koyo)
Outer bearing L44649R, outer race L44610 (koyo)
(UFP kit 07007U0)

Seal size is 1.688" x 2.328" x 1/2" wide. Should use a double lip seal, UFP 07027U.
