1957 Cadillac Fleetwood

1957 Cadillac Fleetwood

Long-wheelbase Cadillacs came in Fleetwood limousine or nine-passenger sedan configurations, both with auxiliary seats. Side trim was the same as on Series 62 models, except that no Cadillac crest was used on the rear fins.

I. D. NUMBERS

  • Serial numbers and engine numbers were the same again.
  • They appeared
    • on a boss on the front right-hand face of the engine block;
    • on the lubrication plate on the left front door pillar (1953-1957)
    • and on the right frame side member behind the motor support.
  • The first pair of symbols were "57" to designate the model year.
  • The next two symbols indicated series as follows:
    • "62" = Series 62 including Eldorado Specials
    • "60" = Series 60 Fleetwood
    • "70" = Series 70 Eldorado Brougham
    • "75" = Series 75 Fleetwood
  • The immediately following numbers, beginning at 00000 for each series, indicated the production sequence in consecutive order.
  • Ending numbers were the same for all series since the engines were installed in mixed production fashion.
