Hey Mike,
In order to find the correct replacement bearings for your spindle we'll either need the serial number off of the axle tube to look up the build sheet or you'll need to measure the spindle with a caliper # PTW80157 at points B, C, and D for the inner diameters. For the outer diameter of the bearings and seal you'll measure the bore hole of the hub.
Let me know what you find and I can look for the correct replacements for you.
