Look in this forum for a thread called
"Closeups of Torsion Bar Install" for pictures if that'll help...
The "fingers" are probably just that - the part of the rear anchor where the adjuster bolts go through. While you've got them out, clean the threads and lightly grease the entire bolt.
As for the L/R markings, you've checked both ends of each bar? There might just be one bar marked - which was the case, IIRC with my recent install. I forgot which way the stampings go... Brent or Synchro - someone had an illustrated HOWTO with that info. Check
http://4x4lo.com under "Mods" also.
