Ah, yes - what fun! Unless you remove the dash, it's a real bear. Even then, it's no picnic. Been a while, but if memory serves...
On the passenger side, if you remove the glove box, you may have a better shot at it. And on the driver's side, try pulling the brake warning light thing (if so equipped). You may have to loosen the outboard dash mounting bolts so you (someone else, really) can pull it out a bit, as well.
Maybe someone who's had a bit more fun with them will chime in with more help.
Good luck!
