Eldorado Cadillac Models & History 1963
Amore distinguished-looking Biarritz arrived for 1963. The lower body “skeg” lines of 1961-62 were erased on all Cadillacs, and wide brushed-finish rocker panel moldings gave the Biarritz closer kinship with the svelte Sixty Special. The price remained stable — a nominal two dollars less than the year before — and production, though still limited, increased significantly.
Model 6367E, the Eldorado Biarritz convertible, had special styling with untrimmed body sides, full-length stainless steel underscores and a rectangular grid pattern rear decorative grille. Power vent windows, white sidewall tires and six-way power seats (in bench seat mode) were standard in Eldorados.
I. D. NUMBERS
- Motor serial numbers took the same form used in 1962
- the first pair of symbols changed to “63” to indicate 1963 model year
- the next symbol was a letter to indicate the model as listed below
- the next six numbers indicated the consecutive unit number beginning with 000001
- The serial number was located at the front of the lefthand frame side bar
- Motor serial numbers again matched and were found on the center lefthand side of the block above the oil pan
- The alphabetical body identification code “C” was no longer used, since the short-deck Town Sedan was dropped from the 62 Series
- However, the short-deck 6300 model, called the Sedan DeVille Park Avenue, was retained and used the same “D” body identification symbol
- Rooflines on two-door hardtops were restyled, which brought a change in body style coding, but not in the alphabetical suffix
