1970 Dodge Dart Dash Removal

It's best to remove the windshield so you can get to the bolts along the front of the dash...

If you are just trying to verify the wiring, I would recommend just pulling the cluster... Pulling the whole dash is much more work, especially getting the heater control cables hooked back up... You can get to the wiring good enough by pulling the gauge cluster... You may want to loosen the bolts that bolt the steering column to the dash to let the steering column lower out of the way to make more clearance to get the cluster out...

I have a 70 Dart dash out of the car I can get a few pictures for you...
