Saggy top

No problem Valentin
With the AstraJ GTC being a 2 (3) door car, its difficult getting the angle right to remove the headlining through the side / only door due to the angle of the door when opened.
As the Omega saloon is a 4 door car, the angle of the rear door when opened gives a clean exit route for the headlining at a 45° angle with the front seats removed.
Glad this bit of information as to how I removed the headlining from my Omega saloon without any damage was of some help to you

They go in before the glass so that's the official procedure. And arguably the best approach.

On the Omega they sit on tabs along the roof frame and hook on from the front so need to go forwards before they fall down. But you need to strip ALL gubbins from the pillars etc. Use the weight of the roof to pop the centre clips.

If it's only sagging a bit at the back, just drop the rear trims and attack it in situ.

Your back will thank you and Bostik spray contact adhesive will get the job done but spray both surfaces and wait for it to dry before attempting stickery.

On cars this age it's usually the thin foam layer between the fabric and the board breaking down with heat and age, so the glue has nothing left to hold. A leak can do it too, so check for stains or a damp smell and the sunroof drains johnnydog mentioned if you have one. When it gets retrimmed make sure all the old crumbly foam is scraped off, new glue on old foam lets go again quickly. A decent trimmer will use foam backed headlining material and a heat resistant contact adhesive. Cheap spray glue tends to give up in the first hot summer.

I've been quoted £700 + vat to have the headlining replaced, or half that if I get it out myself....... I'll be waiting until it gets a lot worse!

yea im with you on that .
however as mentioned above if its an area that can be reached in situ then thats a possibility or maybee someone has one from a breaker ?
