Yup.

"For 1971, only the LeBaron appeared, again in two and four
door hardtops. The Six-Passenger Four-Door Hardtop went to
10,116 ($6,276) customers while 1,442 chose the Six-Passenger
Two-Door Hardtop ($6,044), totaling 11,558. Weights ranged
from 4,705 to 4,855 pounds riding on L 78 X 15 tires.

Imperial had a first in the form of an optional four-wheel
anti-skid braking system ("Sure-Brake" by Bendix at $250 or
$351.50; sources differ). A sensor at each wheel, an
electronic controller, and three vacuum modulators detected
impending wheel lockup and pulsed hydraulic pressure to the
brake.

Years ahead of the industry, the system featured an automatic
functional check when the engine was fired, plus instrument
panel lights to announce that the system was operational or
that there was a problem."

Possibly.

But for production passenger cars, Chrysler was offering one in 1971
through at least 1973. That beats your claim of the Ford Granada in
1985.
