Help with headliner clips

[Mark1972]

Hey all. So the picture below is of the headliner clips i have. The left one is 1 of 12(6 per side)that holds a trim piece on. The other(black ones) I ordered with some other stuff from Year One. They are also called headliner clips, and have little serrations on them. As I've said before, this is my first resto and definitely first headliner. Do the little black ones just go onto the roof rail and then you squeeze them to pinch the headliner in place?(along with glue or course) If anyone could fill in the blanks I'd sure appreciate it.

4-6 on each side....The headliner is glued and they were used during the assembly process to ensure it stayed attached while the glue cured....I still use them but once the glue is cured you don't have to have them...
