it's gonna be much much easier to remove some dash pieces first
on the driver's side: the plastic under the steering wheel, the metal plate beneath that, and you'll have to pop up part of the flat dash piece that runs lengthwise on the top (held in with clips, just pull upward)
passenger's side: glovebox, pop up the flat top dash piece
i can't remember whether or not i popped out the plastic pieces holding the vents, i remember removing some screws around them though.......but after that, the A-pillar and B-pillar trim are just held in with metal clips. The problem is that you have to yank on them pretty hard to pull them out, chances are you'll break at least one......don't forget to remove the "oh shit" bars first too on the rear/passenger seats
