Does anyone know what this door bell looking thing is? Is it stock? It’s below the driver side A/C vent.

Congrats, Tony! That is an award you will cherish forever!  Back to the garage antenna opener, I love the old retro upgrade stuff. Pretty cool. This reminds me that I have a "What Is it" item from a prior parts car I need to post sometime. 

When I bought my car, it had some of the wiring and that same box next to the horns.  The labeling was all gone and I had no idea what it was so I removed it.  Inside the box were some electronics and a couple vacuum tubes, I assumed it was some type of amplifier.

Glad the mystery is finally solved.

We have seen this posted here once before. I believe it was a golden circle transmitter and it took me a bit of online research to find out what it was. 

I moved this to our Trivia forum for future reference.

Thank you --Thank you --Thank you --
Everyone who lives here --know how near and dear the --Golden Thermostat --IS TO ME !!!!! ( for the fiasco i caused on -that thread )
I will be putting this on my Shelf -- next to all the other Cadillac restoration parts ----that i Do Not have !
This is the experience of a lifetime For a -- 64 Cadillac Crazy --guy

The Jury is still out on my end --on weather the 64 - 429 runs better on the 195 degree thermostat over that of the 180 degree thermostat
I did go back to the 180 --and will be checking this out myself but will need some time to compile my results
I have learned that all the newer cars today run thermostat in the 200 degree range due to the fuel injection - computer systems and the metal alloys used in todays engines
I was surprised to learn that fact in my quest for the perfect thermostst temp for our cars
The only difference i find so far is the 64-429 runs 10 degrees cooler on the 180 degree thermostat than that of the 195


Congratulations Tony! By the way it's called a termistate lol. I was talking to a friend who owns a engine rebuild shop and does race engines also. He says they should run at 210 for peak performance. So that seems to be a little vindication for you sir. That would appear to be two golden termistate awards.


Thanks very much for --your support -and thoughts on the termistat temperature subject
I have a high regard for your opinion watching you do your own restoration and picking up some good info from you along the way
Race engines running at 200 degrees --is new to me -as i did endless work to get my Super Stock Drag Race Chevy to run at 160 degrees ( class record holder for 4 years --so it worked for me )
So as you can see running the 64 Caddy at the higher temp actually goes against my thoughts on the temp to run your engine at for peak performance
What kind of race engines was he building and for what kind of racing as that could influence the temps he chooses to run his engines at - i would think

I will be switching the different temp ratings to confirm my thoughts on the subject but it will take me some time to compare
I truly remember --feeling a a bit more performance with the 195 --right after making the change --some years ago in 2006 but will be checking this out for myself

Put the 180 in the car a 3 months ago
The change may be more noticable to me when i change back to 195
I will see


Hey Clovis

If nothing else --i finally learned how to spell--THERMOSTAT --the right way !
Now thats ---a WIN --Win--FOR SURE !------ PMSL !!!!!!!!!!!!!!!!!!!!!!!!!!!

Kevin --will be enjoying this ---i think somehow ( you know --the very CLASSY FLEETWOOD Cadillac English Professor GUY ) PMSL !!!!


and don't you forget it either. LOL

Only just put the Fleetwood back in the garage too.

To get back to the ---Door Bell button
Well its purpose was --door related ! ( and just a very lucky guess on my part )

This has to be one of the earlier garage door openers -- ever -to be in our year cars
Kind of a newer high tech electronic gaget in these years
Boy has time marched on with that item


Is it a dealer installed option or an aftermarket item? At least now I know what those are. Thank you everyone for all the help!

This was not a standard Cadillac dealer installed option. With that said, Cadillac dealers will and have installed aftermarket and other brand items throughout the course of automotive history. (My '02 Escalade has a host of Vogue and other brand equipment installed from Thompson Cadillac, Raleigh, NC)    Regardless, it was probably in all likelihood installed after the original purchase of the car.

64 Recirc/Fresh Air Door Actuator replaced; FROM THE INSIDE.

Posted by Norman Silverman on February 4, 2019 at 11:21pm 8 Comments

I am happy to report that I have successfully replaced the Fresh Air/Recirc door actuator that is located on the blower box-and have done so without having to remove the blower box. I did it by taking out the glove box and attacking it from the back.  It took several days, LOTS of patience and some band-aids, but it is done. THE most difficult part -BY FAR- is to remove and then replace the screw that sits on the actuator arm, connecting it to the fresh…

Where do the flashers go in my 64 Deville Convert.  I'm thinking that's why both turn signals stopped working.

Posted by Norman Silverman on January 9, 2019 at 4:23pm 4 Comments


Where is the best place to purchase good quality motor mounts/trans mounts for my 1964 SDV? I see that Rock Auto has them for $8 and change, and others for $24 and change. Big difference. Is there a better place to buy them from?
