66-67 Dash Removal pictorial

I had to removed a dash from a 67 Olds yesterday. This car was an F85 but the procedure is the same on Cutlass, 442 and Vista cruiser. This is a low option car with only heater no AC. Needless to say the more options the more stuff there is to work around.
I'm not sure how to post a link to here maybe one of the moderators can do that. If you go to my facebook page "Olds Parts and More" you can see it. Hope it helps those pulling a dash. I am not the best mechanic but have pulled a few of these so hopefully my experience doing these will help someone.

Constructive comments or questions are welcome.

Great write up... I copied all of your pictures from Facebook to here, as some people do not use it:

I pulled a dash on a 67 Olds today. I took many pictures and tried to do so as to help others that have had a hard time getting these out. This is not really that hard. Except for one nut. The one above the wiper switch. It is a hard one to get to. This one was removed from a car that has 71,000 miles. Yet it is 50 years old. The insulation on the inside of the firewall was in very bad shape and was all over the place so had to deal with that. I am not putting this back together so I removed the glove box door and liner to help with access. You do not need to do this to get the dash out. I also removed the radio you will need to do this. I took the heater control cables off at the heater box. If I am changing out a dash then I take the three screws off that hold the heater controls to the dash instrument panel (IP) I unplug the electrical wires at the heater controls and the lighter. I removed the tumbler from the ignition and left the ignition switch in the car. It is very hard to unplug. This car had some added on speaker wire that was zip tied to the dash wires so had to remove that. The nuts that hold the dash to the metal frame of the dash are 3/8 and I use mostly a flex head 1/4 drive ratchet and a deep socket to get them off. There is two on the right side, one upper and one lower at the end of the IP. There is also a few more along the upper and lower parts of the IP. On the left side there is two, one above the wiper switch, (this is the worst one to get to) and one below the headlight switch. You also need to unscrew the speedometer cable and with great care undo the circular plug in at the printed circuit. This take your time with and often it will break off a pin or two. The more time and care you take the better the odds of reducing this from happening. This is hard for those of us with neck issues and hand issues. So, take your time and do not be in a hurry. After you get it loose and wiggle it way from the firewall there is a screw that is vertical holding the wiring harness to the top of the speedo cluster area. Another way to do this is to removed the entire wiring harness with the fuse box. This is done by removing the screws on the inside at the fuse box and on the outside at the bulkhead connecting for the wiring harnesses.

To start the removal of the dash I removed the front seat and laid shipping blankets on the floor to make it more accessible and move comfortable to work on.

Glove box prior to removing the door and liner.

Glove box opening with door and liner removed.

speaker wires zip tied to the factory harness. These are not factory and were removed. You may find many things altered on your car. These are 50 year old cars. If they could only tell us their story.

Radio plug in, unplug this and the antenna wire prior to removing the radio.

5/8 socket to removed the nuts on the radio **** shafts.

Radio loose

Most of the screws on the dash are either 3/8 or 1/4 inch sockets. I used a flex head ratchet and a variety of extensions.

ash tray mounting bracket, this does not need to be removed but helps with more clearance and access. again I am not putting this car back together so helps to removed all I can for access.<br/>

Here you can see the 3/8 nut lower center in the picture. This is what he mounting nuts look like. I believe there is 7 of them

looking towards the heater controls from the glove box area you can see another mounting nut in the lower right area

removing the heater control cables at the heater box. a 1//4 inch screw and a slide on locking washer need be removed. I find just take pliers and squeeze the washer. This makes it come right off and in if reinstalling you will need no washers.

and example of a not factory speaker that needed to be removed. These are 50 plus year old cars and will have things at times owners have added

This is the area by the ebrake light.

headlight switch

Here you can see the mounting nut below the headlight switch

You can see how the insulation is in poor condition and gets in the way, You can also see the not factory speaker wire and the round circuit board plug in on the back of the dash

back of the heater controls

This is the screw you can access after you get the dash loose from the firewall.<br/><br/><br/>

removing the screw holding the wiring harness<br/>

Here you can see the speedometer cable and past it the round circuit board plug in

straighten out a large paper clip to insert into the ignition tumbler to remove it

with the key in the tumbler insert the paper clip into this same hole then turn the switch to just past accessory, then pull the tumbler out.

Once this is done the ring can be removed holding the ignitions switch assembly to the dash

Here with the dash assembly out you can see the lower mounting stud to the right just below the headlight switch and to the left the mounting screw for the dash IP to the dash pad

The mounting stud between the speedometer and the heater controls.

the mounting stud below the center area of the dash

The mounting stud on the upper section above the radio

Mounting stud above the lighter area

mounting stud above the wiper switch. This is the hardest one to get to when in the car

yep been there done that. The small mounting dash fasteners were a challenge indeed. When I reinstalled the finished product-dash, I used star-nuts with external tooth lock-washers. I did not want to take a chance of one of them coming loose and get a "dash rattle or squeak". I installed all of the other new wiring needed for all the new accessories, used "ties" to make the job clean and accessible in case of service needed. For a novice I think it turned out pretty good. Is your old fuse panel any good?

The Cutlass looks very similar to my 67 Delmont. Was having fits, trying to get ignition tumbler out last fall. Now that weather is starting to warm up, will give it another shot.
Will be following the pictures as I need to get the dash pad off to get it re-done, due to all the splits and cracks in it. This will help in getting what instrument panel lights are not working back in operation, also.
