1975 Nova Parts and Restoration Information

Known as the “most changed” Chevrolet of the year, the 1975 Nova entered its fourth generation smack dab in the middle of the 1970s. Though the car maintained a similar look to its past generation models, the Nova now had more of a European flare.

Maintaining its 111-inch wheelbase, the 1975 Nova received a larger front stabilizer bar and saw an increase of 1.5-inches in its front tread.

Steel-belted radial tires and front disc brakes were now standard on the model, in addition to a new front-steer and revised subframe setup, which is very similar to that of the 1971-1980 F-body cars (Camaro/Firebird). In fact, every front end component from the X-body Nova can be interchanged with those on the second-generation F-body cars.

The rear suspension for the Nova was carried over to the 1975 model from the third-generation cars.

Inside, the new Novas featured cut-pile carpeting, once reserved for Custom Series Novas, redesigned front arm rests, and a new speedometer with larger script.

Thrusting the Nova into the luxury car market was the top-of-the-line Luxury Nova, or LN. Wide-back reclining front seats, a day/night mirror, electric clock, map pockets and additional sound-deadening insulation are a number of upgrades the LN model featured.

The SS option was also available on the 1975 Nova model, although this upgrade merely added Rally wheels, a blacked out grille and SS emblems.
