Pull the headliner, be carfull it is dellicate, remove the fabric, carefully. Now get a soft brush and get all the old foam off, try not to remove the plastic, now go to fabric shop, they sell headliner-material, buy what size you need and get 3m spray adhesive, get the good stuff!! I laid mine on the floor put the new material over it and started the back 1st, fold it back spray and smooth with hand. I used clothes pins to hold it in place, Mine looks like new, Just take your time and it can be done..
