to replace the dash speaker, you just need to pull off the top of the dash board.
There are 6 screws on the 71-72 cars.
look underneath the dash pad and you will see 3 screws on the drivers side, 3 screws on the passenger side above the glove box, and 2 screws are in the center panel above the map light or A/C vents or storage box if equipped.
if you have a deluxe interior:
from the drivers side remove the outer screw and the inner screw, leave the center screw in place.
from the passenger side remove the outer screw and inner screw, leave the center screw in place.
remove the 2 center screws from the center console.
the dash pad will now be free, push up on the dash pad to make sure the front is free from the dash frame.
now with some effort pull the dash top with pad towards the rear of the car.
there are 3 clips that hold the dash top under the windshield. they will release and the top of the dash can be removed.
if you have a standard interior remove all 3 screws on both sides and be careful about the trim piece under the dash pad on the glove box side take care to remove it and not break it.
the dash top will release the same way.
73 dash tops have extra screws under the windshield that must be removed to allow the dash top to be removed.
removing the dash top will allow access to the AM radio speaker.
FM/AM radio speakers are located in the doors not the dash.
The glove box insert can be installed with out removing the dash pad, there are 5 button head screws just inside the glove box door on a plastic trim piece this trim piece is attached to the glove box insert, remove the screws then pop out the plastic trim with your hands and the cardboard glove box insert will come out with it, its attached to the plastic trim with large staples. the insert for A/C is smaller compared to the Heater only car but the replacement is the same.
not sure which center console you want to replace, the floor console is held on by screws through the carpet and 2 electrical plug that must be disconnected.
if you want to replace the center console in the dash board:
you need to loosen the dash top as described above but you don't need to remove it you can work around it.
to remove the center panel of the dashboard:
set parking brake.
if you have a lower console it will make things easier to remove it. see above
if automatic push the gear select to 1 to move it out of the way.
if manual move shifter as far rear as possible.
first remove the radio panel:
pop off the 2 chrome radio buttons, and remove them and the chrome discs behind them. pop them off bare handed don't use any pry bars. loosen the 2 nuts where the radio controls were use a deep socket hex. there are Star washers behind the nuts. don't lose them. with the front of the radio now loose.
there are 4 countersunk screws on the metal frame around the radio use a short phillips screw driver and remove them 2 above the radio, and 2 above the climate controls.
the metal plate that houses the radio and lower climate controls can now be removed.
optional remove radio: reach behind radio from passenger side, you will feel the antenna connector on the right side, pull it towards the engine bay to release it. reach on the left hand side of the radio and disconnect the rubber power plug.
the plug has no clips you just pull it apart. there will also be a connector for the speaker or speakers. the AM radio is a flat 2 prong plug the Fm/AM is a square plug with 4 connectors.
pull radio forward with some force there is a large metal clip that holds the back of the radio to the dash board frame.
the radio can now be removed.
now things will be different if you have just a heater equipped car verse a A/C car.
remove the large plug on the left side that runs the blower fan there will be 2 more electrical connectors 1 for lights the other for the A/C compressor if equipped, the A/C connector is a red 2 prong connector.
IF A/C equipped
with the electrical disconnected now reach around to the back of the climate controls you will feel a large rubber connector with vacuum lines coming out of it, this is the vacuum octopus it is a push in connection carefully work it off the back of the climate controls there are 2 clips that are part of the octopus that can be a pain to release but if you work it carefully back and forth it will pop out and then you can pull it back off the manifold and release it.
next release the screw under the glove box on the heater or A/C box where the cable with wire come out this will allow you to release it freeing the center console.
carefully look behind the free panel and if equipped with center gauges there will be one large connector to release.
if you have a map light unscrew the 2 counter sunk screws and disconnect the plug. remove the map light as a separate part.
remove the center panel with with the climate controls still attached.
there will be 4 hex screws that hold the climate controls to the plastic center dash panel. remove them and carefully pull the climate controls out from the front.
transfer all hardware and clips from the original center panel to the new panel then reverse dissasembly.
the first time you do it allow for a full weekend and take it slow, it takes me about 4 hours to remove and install one.
well i don't have many photos but this is what you can expect:
you don't need to remove the steering wheel unless you want to work on the instrument cluster on the driver's side.
if you have a deluxe interior you do not need to remove the panel on the passenger side around the glove box to access anything, unless you just want to replace the surround with a new part.
