Rallye Dash Resto
I have a 66 Barracuda. I have completely re-built/painted the dash.
I have to remove 3 large screws around the main part of the dash, and the screws that hold the heater plate on. I had to use a allen wrench to remove the heater control knobs. Behind the heater plate there are a couple more screws. You might need to remove the ignition switch bezel. YES You have drop the steering wheel column. Un-hook the speedo cable. Remove the headlight switch, wiper switch (if necessary). There are probably some wires that are held on with nuts, and other plugs that just push on/pull off.
Be careful not to push on the faces of any of the gauges, and you might want to put some masking tape on any area that will come into contact with the steering column, and also on the column itself to keep things from getting scratched.
While you are doing this, you will want to take the time to check all of the wiring, connections, plugs, bulbs, and do any cleaning/painting necessary. Lubricate the speedometer cable, and check for any needed lubrication on the speedo gears, or whatever.
Save yourself the troupble of having to go in there again.
"DASH DIVING" is not fun, but I've been into my dash so many times I can almost do it blind folded.
