Replacement of Plastic Guide Strips on Rear Bed Slide

[Burquena]

I wanted to ask is there anything special to replacing the plastic strips that "guide" the rear support bars other than just removing and replacing all those screws. On our 2nd trip out with the TM, one of the bars jumped out of the track and put a real nice dent/ scratch in the bottom of the slide. The strips are warped and brittle, and a small piece at one end has broken off. As far as I can tell, it looks like just removing the old and reattaching new strips - is there anything else hiding under there I should know about?
I am taking my TM up to the Car Show in Colorado Springs next week to have the lift system tuned, and if there is something that should be done as far as adjustment, I can have it done there. I don't want to pay their labor cost to just replace strips if I can do it myself. Advice appreciated as always!
