Started the Interior Restore this weekend...
Background: It was my dad's 77, 52k miles all original, L-48.
- Fix map pocket
- Replace Speakers
- Install restored original radio
- Replace shifter and gauge consoles
- AC vents
- Clean all airducts
- Restore HVAC Controls (Was originally gonna replace, but the on I have is functional, just worn-out.)
- Clean shifter boot
- Replace PW switches
- Replace Defrost Switch
- Clean everything
- Completely Replace Ash Tray
Next Month:
- Carpets, seat-repairs, driver-side console, steer-column restore, steering wheel restore.

Changing the right side speaker is not a problem; but changing the one on the left side is a "bear". Your best approach is to take screws out of the driver's side dash panel (all of them), remove the [right side] bracket screw from the top dash panel, lower the steering column a bit, and pull the top dash panel away from the mounting clips. At that point, you can just weasel-in a hand to get the old speaker out and the new one in. Also, the impedence for the new speaker should be 10 ohms, or close to it. Most new auto speakers are 4 ohm and that is too little impedence to be a good match for your original radio. Your choices are as follows. First, you can also install a [4 ohm] speaker in each kick panel and wire them in series with the new [4 ohm] replacement speaker in the dash...so that the total impedance (on each side) is 8 ohms. That's what I did on mine, and there is no problem with frying the output transistors from having too great an impedence mismatch--plus the sound is MUCH better and fuller by having four speakers providing sound instead of two small ones. I highly recommend this approach. Your other alternative is to buy two speaker 'chokes' so that you can match your 10 ohm amp output to the [new 4 ohm] speaker and have the system be electrically correct. These are not expensive and only needs to carry 2-3 amps on the "amp" side and 3-5 amps on the "speaker" side of the choke.
When working on the heater/a/c control head, be sure to clean the contacts on the two 'reed' switches mounted to the left side of the assembly. Then, you need to make sure the switches work as they are supposed to by making and breaking connections to the A/C circuit as the left side thumb wheel moves through the selector choices. Those switches are really tricky, and sometimes you have to bend/manipulate them so that the correct connections are made to comply with your selection on the wheel.

Your advice about the speakers was key, I was trying to find the impedance on the OE stereo, thanks a million. I'll go with two more speakers in the kick panels, I kinda wanted to do that anyway. I was also playing with the idea of converting the high signal to low and plugging it into a new amp. I think I want to throw a sub in the back and then I could also make a line-in to the amp for a iPod/iPhone.
The HVAC controls work perfectly, I am just cleaning-up the rust and dirt, there is crap caked into all the vowels (the "o" in hot, the "d" in cold, etc.) Ha.
Alan, yeah, this thing is in great shape and has a lot meaning to me as my father bought it when I was 5, it's the first car I ever drove, my wife and went to the prom in it and now I am taking my daughter to preschool in it, I am so proud to be restoring it and I love sending snap shots to my dad as I go.
Great fun... makes we want to quit my job and really crank this out... but I have to take it easy... this is eating-up the cash pretty quickly. I have 3K budgeted over the next 12 months.
Next year will be paint... ugh.
It looks great! This should be very rewarding for you...considering it has been in your family all those years. Your pictures look exactly like the mess I have in my garage right now! I have a 76 with red interior all tore apart! Good luck and have fun with it.
] I was working on that problem (or trying to) but discovered that the amp I had purchased was too large to fit behind the right dash panel. So I have to figure out Plan B.Anyway, good luck on your work and let me know if you have success with the aux amp idea. I would suggest that you leave simple 4x6" speakers in the dash area and put 5x7" or 5-1/4" round speakers in the kick panel area. Those larger speakers should be 2-way speakers for mid-range and bass, and the dash speakers should only be for treble (or just inexpensive 1-cone speakers). That way, the treble is coming from the dash speakers and being reflected off the windshield [glass is very effective at reflecting treble range frequencies], and the lower speakers can handle the bass and mid-range frequencies. It works quite well and you don't have to put any crossover system in place to make it work. Also, all of those speakers should have low power ratings (under 30 watts or so). The Delco amp only put out 16 watts (RMS) and if you put low efficiency speakers [high watt capacity], you won't get much sound out of them. Anyway, low power speakers are less expensive...right? Now, if you figure out the aux amp situation and have power to burn, go for the inefficient but high-clarity speakers!!
Finding a place for the amp will be the real trick.
I am doing the speakers like you said, larger, lower freq one in the kickers and higher freq in the dash. Since I plan to amp it, I got some fairly nice Polk speakers.

- Intermittent Wiper Controller
- A Kenwood Tape Deck, stereo (from 1981-ish)
- Power Antenna Switch burred through the Gauge Console
- 6x9 Speakers from the 80's just leaning against the wall inside the rear deck.
- He replaced the carpet once, so there are a bunch of stripped screws, I've had to drill out the sill plates in three places.
Fun, fun!
Fun, fun!
Last month I was going to fix my tachometer by installing a new circuit board. Before I was done with that project I had all new dash light bulbs (there are dozens and dozens of bulbs back there!), removed the stereo and sent it off to be restored and installed new speakers!
It is like it never ends...but it is fun!

Enjoy!
in certain places. I highly recommend this purchase! It makes life easier and certainly a better finished product.

Thx!

If you remove them - just know that the door is extremly heavy! have help!
