I took my out completely because I put a tilt column back in it after I finished the dash. You should have plenty of room after taking the bracket off.
I take it loose enough for the wheel to sit on the seat. I let it lay on my legs as I took the dash out.

If you are replacing the harness ask your self if you are happy with the firewall insulation pad and check the condition of your heater core box seals and any other firewall grommets. As long as you are in there replacing the harness if any of those items need to be replaced now would be a good time since you have it all apart. Also suggest buying all new bulbs for your instrument cluster, turn signals, bright lights, etc. Pulling the front seat obviously gives you a lot more room, I like using a cheapie harbor freight moving blanket to lay on and one of those led lights on the head band come in handy. Some blue painters tape to protect the dash. I personally would pull the column out even though its NOT NECESSARY it just makes things easier as I have big hands and its just less aggravation and cussing than the 30 extra minutes to pull it. Be sure to pack the engine side of the bulk head connector with dielectric grease to keep corrosion away.



Thanks for mentioning the firewall insulation. Mine is in terrible shape and needs to come out for sure. As soon as I touch any part of it, I get a crumbled yellow mess to vacuum up. I'm really not looking forward to doing replacing this pad. It looks to be a huge PIA but it needs to be done. Any one got any tips for that? I saw Hubbard's sells the pad and the plastic clips to hold it place. $60 for both seems pretty reasonable.

Oh, the mess its gonna make.

Push the plastic tabs through from the outside where possible and remove all of them befor removing the pad. Put a blanket over the carpet as close to the bottom of the pad to catch the crap.

I’d remove the steering wheel so you don’t have to lean over it and work around it when pulling the dash.

Do not buy the cheap firewall pad...... The cheap ones are junk.
The best firewall pad costs over $ 100 and is worth every nickel.

I sent back the cheap one for my 62 to Ecklers for a refund(It was black(Not gray), it had the wrong width seal along the bottom and was the wrong color. The cheap one was not molded to fit the firewall in 61 and 62's.

You may need a special firewall push in tool (that fits the ribbed push in clips)You really need it install the plastic push in clips. Without the tool you will drive a round philips right through the end of the clips - the Ribbed clips are really hard to install straight and get them installed without ruining them.

On the hunt for the quality one now. I searched the forum and a few years back, Phil Reed from Kansas City was recommended as someone who sells the quality pads. I just emailed him.

Anyone know of any other sellers? Thanks

Thanks Paul, I will check that out. So my last question....

I currently don't have A/C but will be installing a Vintage Air System at the same time as replacing this firewall pad. Is it still OK to use the non-A/C pad or will I have to modify it?

All firewall pads come with the heater area filled in with regular firewall pad with the outline of the factory non air inside the firewall heater box. The area has a perforated lines on it to make it easier to cut. The lines in the firewall pad are for a non factory air firewall opening for the heater. A factory air firewall opening is about 3 inches smaller than a non factory air firewall car.

This area can be cut out in any shape -it won't be easy without using the marked line(that is already partially cut) but if you have a really sharp cutter you should be able to to it.

See my pictures above of the firewall pad inside the car that was removed to mount the factory air heater core.

I was going to ask a question about the Factory AC cars but you have explained everything I need to know.
The photos are always a big help.

My Wife Sews/Quilts so she will be doing the cutting for me

Thanks Paul

Paul,

Thanks for that info and the pictures. So was checking out the website and also saw they sold this product:
https://carsinc.com/molded-firewall-pads- 22326.htm...

Do you think this one is for a car with A/C and may not require much modification? There was not much in the description but it not say "without A/C". I tried to call the company to inquire, but they did not answer. I'm going to follow up with an email as well.

Thanks again for all the assistance. You pictures cemented the fact that I need to remove the heater box prior to installation. It is getting replaced with the vintage air anyway so that's one less step I have to do when I tackle that job this spring.

I did find the 10% discount they are running through the holidays. Enter "HS18" when checking out for others who may be interested.

To cut the firewall pad not on the perforated lines may take a shears or a very sharp -strong scissors.

I do not think you will find any firewall pad for a 61 to 64 for factory air condtioning or even paritally cut for A/C. The firewall pads come covering the entire inner heater box area for 61 & 62 for sure. You will probably have cut them.

I have cut at least 5 of the best quality firewall pads on frame off restorations. Two of them were 62 factory air conditioned cars.


In fact for 1962 pads you have to cut the pads (that are already marked) for the gas pedal linkage, back up lights, parking brake, small hole for the factory heater box long bolt. 63 pads may have some of the holes cut for these items
If you are doing a 63 this might help
from Ecklers (to expensive when compared to Cars)
https://www.lategreatchevy.com/full-size-chevy-fir...

I do not see this one cut for factory air to match a factory air firewall in 63

I collected 4 or 5 1961 1962 factory air units over the years still have parts left.

I have a friend that has not finished his vintage air in his 62 Belair 2 door. There is very limited room under the dash for the vintage air unit -extremely tight.

Thanks for the 10% off code.
I might have to order this sooner than I wanted to.

Have to see how much shipping will be.

I had a heater core cleaned and checked for leaks in preparation for replacing my heater shut off valve. When I got mine out, I found that it was smaller than the one that I had repaired. What I learned, is that the 1961 and early 1962 heater cores are larger than the later 1962 heater core. I had my smaller one cleaned and checked, and installed it back into my car, since I couldn't find the larger heater core steel frame at the time. I have since located it, and now I have a spare should I ever need it. Another item that isn't made for the air conditioned cars is the foam seal for the water tubes, nor the rubber gasket. I find it strange that so many of these simple items are not available.
This heater nipple gasket is available from Inline Tube, and sells for $3.50 plus $1.75 shipping. They say that it fits 1964-74 GM cars. I think that it might also work for the 1962 Chevrolet also. Looks correct to me.


Never argue with an idiot. He'll drag you down to his level, then beat you with experience.
