Leaking drain holes into cabin

[jts46]

Finally replaced the 90' connecter (7H7875537C) and roof lining over front cabin dried out, as a consequence the fabric of the roof lining has separated from the backing, see attached photo. I have tried contact adhesive and double sided tapes but none work.
What i would like is information of the part number for the front headlining and any idea of the cost. @VW Guru : would your company be ok with doing this repair. The front headlining is also badly stained.
I realise it will be expensive but i intend keeping the van until ?????????
