Has anyone installed Olympic A/T Sliders on their JK?

I ordered the Olympic A/T sliders and just received them yesterday. The directions were on one page and don't tell you much. There were two approx. 3" by 48" rubber strips in the box. Does anyone know if these rubber strips go between the slider and the frame to prevent rubbing? I presume that they do, but directions don't mention them and I want to be sure that is what they are intended for.

Any input/feedback on this would be great and appreciated! I WILL post pictures after they are installed
