As mentioned, but you need to do some dissasembly first.
Mine are repaired, but I didn't remove the foam.
1/ pop out the light lenses.
2/ remove the two phillips heas screws. #2 size.
3/ carefully wiggle and unhook the mirror/light assembly.
4/ disconnect wiring.
Once off the visor you can work a lot easier on it without risk of messing up the visor itself.
You can also swap in one off a 3000GT as the flappy, mirror assembly bit is the same
If you are going to stick it, you can spray carpet adhesive now onto the back of the hard visor flap and smooth the fabric and foam back onto the lid. When I did mine I used masking tape and clothes pegs to manage the edges so it sat tight as the glue was properly hardened.
Once glued overnight, reassemble in the reverse order. The one in my green car was done about 40K ago and has been perfect ever since. The lightup mirror is a feature my wife likes
Hope this helps.
