If the spindles are in good shape, I might be interested in both.
One will need to remove the brake rotors to know if good or not. The problem with spindles is when a wheel bearing fails it (more or less) welds itself onto the spindle or eats it alive.
This is from my '77 wagon back in October 2016 (so a few years back):

The outer (smaller) wheel bearing came apart and inner race decided to weld itself onto the spindle damaging it. The damage is marked in red. There is no possible way of filing that down smooth, again. I have seen this happen to the inner bearing as well and there, you have no room to work with.
By the way, it took a long time to get the bearing off of that spindle. I think I had to use a press, maybe (can't remember).

This is what it looked like once I first got the rotor off. In most cases, the outer wheel bearing wants to come sliding off just after removing the nut - but not this time.
If both bearing surfaces will
not catch a fingernail, then most likely you have a good one (or pair).
