This line reflected Series 62 styling revisions, but incorporated a DeVille signature script above the lower beltline molding, near the rear of the body. Standard features on DeVilles (and on base 6200 convertibles) were the same as on closed body 6200 models, plus two-way power seats and power windows.

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

  • It was also some 37 kg lighter, due to the use of aluminum accessory drives.
