Fleetwood Series Sixty Special Cadillac History 1955

TheSixty Special Fleetwood now had 12 vertical louvers at the rear lower side of the back fenders and continued with a Fleetwood script on the rear deck.

  • directional signals
  • backup lights
  • oil bath air cleaner
  • automatic choke
  • full-pressure lubrication
  • 12-volt electrical system
  • knee-action front suspension
  • hypoid semi-floating rear axle
  • wheel discs
  • pushbutton automatic windshield washers.

I. D. NUMBERS

  • Serial numbers and engine numbers were the same again
  • They were found in the same locations as previous year.
  • The first two symbols were “55” to designate 1955 model production.
  • The next two symbols indicated the series as follows:
    • “62” = Series 62 and Eldorado
    • “60” = Series Special Fleetwood
    • “75” = Series 75 Fleetwood
  • The remaining digits represented the consecutive unit number and began at 00000 for each series.
  • All series had the same ending number, which would be misinterpreted if listed.
