Do cut the hole in the headlining before or after glueing the headliner in?
Do I fit the sunroof in first then clamp the headliner under it then stretch/glue/fit the headliner?
Do I fit the headliner first then drop the sunroof in?
So many ways I could do this... or maybe I should say so many ways I could screw this up

Cheers,
Colin.
