Working on my project Australian XP Falcon Sedan Delivery. I've re-drilled all the holes for the headliner to suit the US one supplied. Have fitted/removed/fitted the thing now a few times and as of tonight I think I'm a whisker away from being confident enough to do some gluing. Overall it's stretched out pretty smooth but I have a few questions for any experts that may be tuned in. Follow along the attached photos & hopefully I will start to make sense.... Front & rear are clamped fairly tight like this Front looking back Back looking forward Here's where it gets interesting. At the roof brace and at the B-pillar, it seems like I need to cut the headliner to allow me to smooth it out where these braces block the gluing flange. These are the only real places where the creasing remains a problem. Is this correct? Can it be done without creating a tear point in the headliner? Also, forward of the B-pillar there is windlace and these toothed clamp plates. I assume I will need to trim along the line of these about 30mm off so that I don't have too much material to push up into the teeth? Also, how best to go about trimming the corners at the A-pillar & windscreen opening edges?
