Horns Used on 1963 & 1964 Cadillacs

In 1963 there were two conch shell shaped horns roughly 5" diameter. One Hi Note and one Lo Note.  They were marked with the 'L' and 'H' inside the lip of the horn.

There was also an optional Eldorado Style "B-Flat" note long trumpet horn offered in 1963. The part # was  199 9947, and stamped 947.

In 1964 there were three horns standard. Two conch shell shaped horns roughly 4" diameter...One Hi Note and one Lo Note.  They were marked with an 'L' and 'H' inside the lip of the horn. There was also a Hi C-Note short trumpet horn standard on all body styles except the Eldorado.

There was also an Eldo Style "Low-C" note Long trumpet horn, standard on Eldorados, and offered as a dealer installed option on other body styles.  The part #  was 199 9896, and stamped 896.  When this horn was installed on non-Eldorado body styles, it provided a unique 4 horn setup.

According to later Master Parts Book (e.g. 1969 MPB) the smaller 1964 style horn were used as replacements as needed for 1963 and earlier Lo and Hi note horns. In fact the Master Parts book shows these horns as being used for 1953 to 1969.

Anyone have a decent radiator and shrouds and hardware for a 1964 Cadillac deville. I have an alum. radiator and I'm deciding on to fix it or back to the original one. If I fix it I won't need parts.


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…
