The even numbered bar (with the R after it) goes on the right side (passenger side in the U.S.) Rather than fight the lower control arm, I keep the nut on the lower control arm pin slightly loose where it goes into the K-member, leave the shock off, and keep the control arm unattached to the spindle. Lower the control arm as far as it will go, have the adjustment bolt backed off most of the way (but still in far enough for it to sit in it's cup) and install the torsion bar. Then tension it up and install the rest of the parts. Keep the nut on the lower control arm pin loose until you get the ride height set and front end aligned.
