I have a nearly new fibreglass headliner to give away, it needs retrimming though.
I bought it this year but the fabric came loose so the supplier replaced it for free. So if you want to replace your original saggy headliner on the cheap you just need to put new fabric on this.

located in Kidderminster, UK.


Cuts in the fabric are where the supplier wanted me to check the failed glue.

 

Send me a PM when this is GONE and I'll delete the thread.
