Hi Brad:
The issue, as I see it, is whether it is a good idea to bolt these things
onto a Dura-Torque axle or not. You should have a solid axle and springs on
your '59 and needn't have the same concern.
Anyone with a Dura-Torque axle that is comfortable with using these
things....more power to 'em.
But I'm not one of them.
