By 1967, the Corvair was evolving in several respects:
Suspension, Engine and body styling.
By 1969, it was an impressive machine, both in looks and performance - but the stigma that was hung around it's neck by Nader and his minions killed it's future.
One of the features of the Corvair that I took advantage of, was it's Saginaw steeringbox, that was 3.5 turns lock-to-lock. I swapped the Saginaw steeringbox out of my 1962 Nova (5.75 turns lock-to-lock) with a perfect fit (chassis bolts, pitman to tie rod, dash column support, turn signal assembly/wiring and steering wheel spline.)
