Used Air Shocks

As long as the '57 has a stud on the shock plate to run through the "EYE" of the shock on the bottom and a bolt up top to run through the top eye of the shock, (or stud, but doubt there is one up top) It will fit.

The shocks length is very long, but very adjustable.

Excellent load leveling device. Use with enuff air for a "slight" rake with a half tank of gas.
