No, the 1957 Chevy didn't come with seat belts.
The answer depends on the size of the people and how comfortable they wish to be. The Chevy Cobalt has two front seats and a backseat which has 46.1 inches of hip room. The Chevy Cobalt's backseat has been described as "small" in the past.
I have a new 2005 Chevy cobalt, it seats 4 nicely and 5 if you want, wouldn't recommend trying to fit more then that.
you cant
Legally, a Chevrolet Cobalt can only carry 5 passengers, however more can fit if people squeeze in tight and do not wear seat belts. This may differ based on the make of your car, and if something is wrong with either the seats, the seat belts, or if people are uncomfortable or unable to sit as close as would be required for all 5 to sit there.
any seat belts from an 1981 through1987 Chevy truck or 1981 through 1989 blazer or suburban
2 in the front seat 3 in the back
Seat belts are unsafe because they can get stuck in a fire. Throw back someone inside the seat belt. Seat belts can choke people.
That vehicle had seat belts in it when it left the factory so it should have threaded holes in the floor where they were once mounted. Purchase aftermarket seat belts for that vehicle and bolt them in.
In the trunk, there are pull levers that will release the seats. One for each seat.
if you sit in the passenger seat it will be by your left foot
you buckle it dardar
