Help needed - Rear bearing/seal/snap ring - 29 Banjo & 37 Wide Five Hub

[Kube]

You can trust Mike Driskell (third gen) fully. I do not believe you will find one man that says otherwise.

You are correct about the repop bearings being prone to failure. Good - used Ford bearings are the way to go.
What is the inside diameter of the drum (seal area)? I did see your thread and failed to respond. For that I apologize. I ask the diameter to be certain you have '37 drums. They appear nearly identical to '36 drums. In '36, two different diameters of bearings were used. I'd hate to offer advice that would lead you to a mistake when purchasing parts.
Modern seals are available and the way to go. NOS seals are often dried out beyond good usefulness. Snap ring needed? I'd vote "yes". Ford was not known for spending a single cent if it were not necessary.
