You prob only have to drop the headliner in the front and will be easy. Take both visor off and miror. Take off rubber around sunroof part of headliner to free it up and the door rubber and it will be able to come down without much strain and it won't break that easy. Could be big dead bugs rattling...lol
that should be enough to see above your head without taking out the a pillars where the seatbelt is. If you can't see enough just drop all the way by taking all apart.
