Replace suspect rear suspension components before they can fail and strand you by the road side. These covers are made to fit over 21 3/4" Torsion Bars that do not extend outside of the housing cover. For the earlier models (1950-1959) your torsion bar is most likely 24 11/16" long and you will need torsion housing covers that have a hole in the center that allows the longer torsion bar to extend through it.
