BODY BY FISHER AND WHAT IT MEANS
The Famous Body by Fisher on every Nova contains new inner and outer body panels, a heavily ribbed and reinforced underbody and stronger, stamped steel door hinges. There's more: The Body by Fisher also contains stronger windshield pillars, a flush-mounted windshield bonded to body metal, fork-type door locks, a concealed fuel filter, keyless door locking, plus many other quality features.
SUSPENSION AND STEERING
This year, the Nova is smoother and quieter than ever before, thanks to a rubber isolated, partial front frame and a cushion-mounted front frame section. An independent front coil suspension design, bias-mounted rear shock absorbers and Mono-Plate single-leaf rear springs help level rough roads, too. The Nova's longer 111" wheelbase and new wider front and rear tread contribute greatly to a road-hugging stable ride. Precise Ball-Race steering with a higher ratio (28:1 overall) makes parking and turning easier.
For all Nova models 14-inch wheels are standard. Ask your dealer about tire sizes, appearance and availability.
