I have a 91 T/A with the Lexan t-tops. My weatherstripping, like most others, is getting old and needs to be replaced. While looking at the parts breakdown, I see you can buy the weather stripping for our cars with or without a "slider". What is a slider. I don't want to get the wrong part.

Does the weatherstripping from gmpartsdirect include everything necessary to do the job completely, or is there more parts/pieces involved?

TIA!!!
