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.

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

Fuel loss in Carburetor

Posted by Ian Osborne on December 29, 2018 at 11:24pm 16 Comments

Lately if I haven't started my '63 in four or five days it seems that the carburetor has gone dry. The starter cranks for an extended period of time and the engine doesn't come close to firing. I have resorted to pouring a little fuel into the carb to save the starter and battery. This gets it started and it runs fine. It also starts fine after sitting a short while - a couple hours or so.

The fuel pump is new and there is always fuel in the glass bowl of the fuel filter. This, along…
