I've always known it as 'back to back'.
A 35A bridge can be had for a dollar or three - cross wire the
connections and you get 70A worth of diodes in both directions and
you'll have a fixing hole to bolt it down and make the mechanics
easy, no need to search for standoffs or tag strips or string
diodes in mid air.
