Accelerator Pedal Plastic Slides

[Leester]

Tried searching - maybe missed it but Authentic Classics sells a piece plastic slide set for the accelerator pedal. When I looked at my old one, I only had one of the two plastic pieces. I assume these enable the pedal to slide more easily on the shaft but I can't quite figure out how they should be installed on the back of the pedal.  Anyone know?  Thanks in advance.
