As I understand it, you're talking about the pivot points for the front lower control arms that have the bushings built into them. They are where the adjustment cams are for an alignment.

Toyota doesn't consider those bushings as being replaceable separate from the control arms. So you need to order the control arm assembly which includes those bushings in them.

One thing that adds complexity to the replacement of the front lower control arms is you have to partially unbolt the steering rack to get at one or two of the rear pivot bolts.

Part of 4Runneradam's comments apply to the lower ball joint, which you'll need to separate from the lower control arm as part of this. Be sure to use blue medium strength thread lock on those 4 bolts around the bottom of the lower ball joint.
