According to Dexter, your axle is old enough (2002) that my contacts at Dexter had some fun going through the old databases looking it up. They were able to find that it's a 7000 lb capacity axle with a 92 inch hub face dimension and 74 spring center to spring center spacing.
They couldn't tell me which bearing sets were used, but we can likely figure it out. A 7K axle will typically use a 25580 inner bearing with a 1.750 inner diameter and a 14125A outer bearing with a 1.250 inner diameter. For a grease seal, the 10-60 with a 2.250 ID or the GS-2125DL are typical. Both seals have the same 3.376 inch outer diameter but you'll want to measure the surface of the spindle where the seal rides to choose the correct seal. If it's slightly larger than 2.125, use the GS-2125DL or if it's slightly larger than 2.250 use the GS-2250DL.
We sell both bearing sets as kits, as part # BK3-210 which includes the 25580 inner and 14125A outer bearing, the inner and outer races, GS-2125DL seal, tank washer and cotter pin. The # BK3-200 provides the same parts but provides a 10-36 grease seal with the 2.250 inner diameter.
Your axle is compatible with 12 inch brake assemblies. A 7K axle would typically use a 12 x 2 inch brake assembly like # AKEBRK-7-SA.
Due to the age of your axle, I'd urge you to confirm the above by using a digital caliper like # PTW80157 to measure the hub bore, bearing ID and the diameter of the surface of the spindle where the grease seal rides to make sure everything mentioned is compatible. You'll also want to measure the inside depth and inside diameter of your hub/drums to ensure the 12 x 2 brake assembly is compatible.
