Removing Dash to access speakers

I trying to figure out how to take the dash off on my 68 dodge coronet to replace the speakers in the dash...any suggestions or input.

You've got to pull the windshield to gain access to most of the fasteners. Drastic unless you need a new windshield. One speaker in the center?, you will have to go up from underneath or possibly remove your gauge cluster and access from the front.

I got to the center speaker in my 70 buy removing the ash tray and radio first. I would think a passenger side speaker could be gotten to by taking out the glove box liner. Driver side may require taking out the instrument cluster. One other hint - it is easier to work under a dash if the front seats are out of the car. Good luck!
