I have never taken the dash off but I have had to remove parts of it. Try taking the glove box out and the lower half of the drivers side off and the center trim around the radio and fan controls off first. You might be able to look up in there and see where any bolts are that hold the dash. The radio should be easy to remove with 4 screws so you can get a better look. Hope this helps a little. If you do get it removed post so we will know how easy it is.
I got the same problems with mines. I'm doin a custom dash and i gots problems takin it off too. All I know is that it's easier to take off the glove box and the panel under the steering wheel first to gain access to the screws under the dash but be careful of the wires that to to the instrument panel. I hope this helps you
