1973 Camaro Parts and Restoration Information

1973 Camaro Parts and Restoration Specifications

The 1973 Camaro saw a nicer interior and the SS, Super Sport option was no longer offered.

Fans were also sadly disappointed to find out that the 396 BB V8 was no longer available.

1973 Camaro was seen as a ‘sleeper vehicle’ when optioned with the more aggressive Z/28 Camaro model options.

1973 Spotters Guide & New Features

1973 appeared bright for the Camaro despite the previous year’s problems and continued turmoil. Sales picked up slightly. While the industry was installing battering ram style bumpers on cars in response to the federal 2.5 MPH regulation, Chevy was able to engineer the Camaros bumper, including the Rally Sport so that it would pass.
The Super Sport model was dropped, but it was replaced with the Stylish Type LT model. The Type LT could be ordered with RPO Z28, and if the Rally Sport option was also ordered, you could have a Type LT/RS/Z28 Camaro.

The Z28 was still being neutered power-wise, but hey, Air Conditioning was available for the 1st time on the Z28.
The times they’re a changing, and so was the Camaro. And for 1973 you saw…

  • RPO Z27 (SS) dropped, replaced with Type LT.
  • Formerly optional steering wheel (NK4) became standard.
  • New impact absorbing bumpers… RS kept bumperettes, but they were stiffened up.
  • Single stick ratchetting shifter replaced stirrup model.
  • Z28 could get air conditioning (due to non-mechanical lifters).
  • New wheel selections….
  • Z87 Custom interior dropped
  • Perforated headliner replaces Cut & Sew style in mid-year
  • Space-saver tire debut
  • Redesigned console
  • Power windows debuted
  • full foam rear seats with one-piece backrest.
  • Powerglide 2 speed automatic trans dropped
  • EGR for all engines & coolant-recovery
  • Warning buzzer/fasten seat belts debut
  • Tail-light housing switched from black to white plastic
