14ff spindle replacement?

[zac]

Finally got the rear axle swapped into my '79 K20, went to pull the drums/hubs/bearings for inspection, found spindle damage on the driver's side. This is the first time I've worked on a full-floater, I'm wondering if the spindles come off like they do on the front, or if they are integral with the housing. If so, I'm stuck with the repair someone attempted, or swapping the gear set from this one into the housing I just took out--dont' care for either of those options. The fact that the keyway is at the 4 o'clock position rather than 12 makes me hope that it has been off at sometime in the past.
