I'm trying to install the SLR Stage III. I'm at the torsion bar stage and need some help. The instructions say that the bars are marked L or R on the back. Mine only say 28 on one end. There's no other markings. Which is the back? Also, the directions say to make a note as to the position of the T-bar fingers. What are these? Even my Haynes manual doesn't mention fingers. Are they the piece that the adjusting bolts go through? I also have two things that look like a knob with a screw - anyone know what they are for?
