RX-2 VS RX-3 Front lower control arms
I'm hoping someone knows this answer. Are the RX2 and RX3 arms interchangeable? I know the sway bars are the same, but couldn't find anything about the arms themselves. Also if they are, are the steering arms the same also?
Thanks in advance.

they are the same I had a set of both and they looked the same including length and angles, steering arms are the same, now the 74 rx4 arms are similar but have different angle at ball joint (less) and steering arms are different as well, same taper for ball joint but different taper for outer tie rod and angle down isntead of upwards and also have a wider spacing ( 80mm) where the strut bolts up, same as 1st gen rx7 thats why they are interchangeable and thats why you need rx4 steering arms and outer tie rods ( thread and pitch is same) if you want to run rx7 struts in an rx2 or rx3 ,1976 cosmo and rx4s that came with power steering have an even bigger taper for outer tie rods and can be used with the cosmo or 76 rx4 outer tie rod but are about 10-12mm longer than the rest, not good for steering angle.
wow that was a mouthful !!!!!!!!!! hope all this makes sense
there are 3 rx4 steering arms
74 manual steering
74 power steering identical tapers but longer by 10-12 mm
76 rx4 or Cosmo bigger outer tie rod taper and longer by 10-12 mm
I would work with an rx4 or rx7 steering arm if you are planning on making a lower control arm and streering arm for an rx2 or 3 because it will allow the use of an rx7 srtut of any year

That is what I thought on the RX2 and RX3 arm. That was the plan on the steering arms of being made to adapt the first gen RX7 shock assembly as like such we can still use the same coil over setup and bigger brake setup if anyone wishes to use those part later on.
Here's another question, would you guys prefering having bushings back in sway bar? or would you rather see a Heim Joint of sort in there? The stock ball joint will be replaced with a heim joint aslo.
