Headliner support bar Q

I’m having my headliner card recovered. On the back lip of the sunroof there is a aluminum bar that runs the length of the sunroof.

It looks like the bar attaches to the roof and the headliner is glued to it..( think) after the card is installed.

My question is, when you have the card recovered, does this piece get glued with the rest? I’m confused.

Also, the little plastic pieces that tuck up into the sunroof right and left. Should I hand those over to the shop who is recovering? .....what a mess that old glue is!!

Thanks.
