Left or Rights?

In that 1st picture, the caliper on the left, are both those bleeder holes threaded? I would think that if all the bleeder holes on both calipers are threaded and both calipers are identical, then you would be able to flip one and mount them on either side.

Why would they have the bleeder on the outboard side, you’d have to remove the wheel whenever you bled the brakes, no?

agreed, bleeder goes on top.
