"I know all about the early Nova's bad suspension" --that sounds like a Camaro guy's line!
They were no worse (nearly identical)than early Mustangs. Put in some '64 or later a/c springs and some station wagon mono leafs and they're ok 'til you try to stop 'em. Now the '64/67's used Chevelle sized brakes and five bolts as did the laterbodied corvairs-- you can also put in 'Vette worm nuts to quicken the steering ratio (more effort though). You Camaro and '68/later nova guys had it made!
