no one in this thread asked for tips on how to install it

but, yes, the rubber goes in the roof first (round/bead side in), then the headliner is put up and the lip is pulled outside of it to hold it up. the rubber shown is exactly like the one i installed. it will go in with some lubricant (i used dish soap), something dull to push it in, and perseverance. there is no easy way to do it.
