We haven't handed out any cigars lately so I have one that I "relearned" today from a visitor with a 63 Eldorado.
So the question is there is a piece of general insignia not related to a specific body style that is missing on the 1963 and 1964 Eldorado and Fleetwood 60 Special but is found on the other body styles.
I can give some hints but will leave it a bit open to see if we have any super sleuths.
I never noticed this before, but just by searching pics it looks like there is no Cadillac script in the grille on those models.
Nevermind. I'm blind
Alright, going for Cadillac script again but it's missing from the glove box.
Also, the 1963 Eldorados have neither a V nor a crest on the deck lid.
Charles that is true but they do have ELDORADO in block lettering on the trunk lid to designate the body style, as does the 1963 FLEETWOOD. So in a way you are correct in that the general 1963 V & crest insignia is not there, but there is insignia for that particular body style. In 1964 the Fleetwoods (including Eldorado) would adopt the wreath on the hood and trunk, and block lettering would be moved to the rear bottom section of the front fenders.
Regardless, Charles also gets a Cigar!!
