And finally got the saggy headliner replaced. It's not 100% perfect but for a first go I'm happy with it. Grey suede effect headliner material from Martrim and a black suede look material for the A, B & C pillars.
I have had the materials sat in the garage since October.
Also the hardest bits to get off when removing the old headliner were the saggy bits I had temporarily glued up to get by, great if your happy to make do but I wouldn't recommend if your planning on redoing the headliner anytime soon. Just pin it up, saves time and risk of damage to the board when removing the old material .
I have material left over I could use for the sunvisors, but basically I haven't a clue how best to retrim them.
