I have the lower stut mounts I think. I call them steering knuckles sometimes. Or steering arms. They go onto the ball joint of the control arm, and have two bolts going through them to mount to the bottom of the strut.
I have two of these for you, off a RA60, plus I have a steering rack.
I think you will find the lower control arms are almost the same as TE72,KE70,AE71,AE86 ones. Maybe a slightly different length, but very similar. Or you could use KE30/XT130 arms and shorten them a bit.
