Notes

The front bumpers were modified from the 1972 model year to withstand new federal 5-mph standards. The updated bumpers added thirty-five pounds of weight to the vehicle.
A forty-percent reduction in cabin noise was obtained by using sound deadening spray on material in inner panels and sound deadening pads on the inner-hood surface.
To reduce road vibration in the vehicle, rubber mounts with steel sleeves were added to the chassis.
An overflow coolant reservoir was added to aid in coolant temperature.
To increase side impact protection, steel beams were added to the doors on the 1973 model Corvette.
The rear window in the 1973 Corvette was fixed and no longer removable. Zora Arkus-Duntov stated that the removal of the rear window created too much interior air buffeting and that this, not the cost savings, was the reason that the 1973 Corvette featured a fixed window.
1973 was the first year radial tires were offered on a Corvette.
The lifting windshield wiper panel was deleted from the 1973 Corvette, but a new hood with rear cold air induction was introduced.
