71 K10 Front Hub Mystery

[2B32]

I kept bending grease seals on the front hub of my 71 K10 (disc brakes) while replacing my wheel bearings. After taking apart the passenger side I realized the hub on the driver's side was not the same. The seat for the grease seal on the driver's side is beveled, where the seat for the grease seal on the passenger side has a flat sidewall and flat lip the grease seal sits on. Needless to say I don't know what the driver's side hub is off of. Are there any years that are a direct fit replacement, or will I have to buy a new replacement?
