So as I work my way through my S5 project car I find more and more little secrets. I have a gap between my A to B pillar trim and the headliner. Finally figured it out today and I’m pretty sure this car originally had automatic seatbelts and someone converted it to normal shoulder belts. So my assumption is the auto belts were wider and mated up with the headliner. I’m sure this isn’t the first car to have this operation performed so does anyone know the fix? I’m sure sourcing auto belts would fix it but no thanks. Is there an answer other than a new headliner?

There is skinnier trim from a manual belt car that is holding the pillar trim but it doesn’t hold the headliner. Looks like the a and b pillars plastic were both replaced.

So is a S4 headliner with sunroof an option? Canadien headliner seems impossible so if S4 doesn’t work, I’m on the hunt for the tracks and trim.
