Trunk hinge sliders

If that's the right name for the plastic parts on the trunk torsion bars that ride on the hinge for lubrication.
How are these installed? Where do they fit on the t-bars? Is there a procedure to do the install?
My '64 Dart FSM has one picture of them and no info. Any info is better than what I have now. Pictures or links to pictures would be wonderful.

Thanks!
