Never going to Auto Zone again

67 Dart GT I decided to replace steering box and went in and asked if they could order one for me. Virgil asked "6 cylinder or V-8 and I asked why and he said V-8 had closer ratio.
This is a new one...All power steering cars had the same 15.7 to 1 steering box. Manual steering? I have read that from 1967 to 1969, a 20 to 1 ratio was offered as a fast ratio alternative to the standard 24 to 1 ratio steering box. To me, I would not consider a 20 to 1 ratio to be fast at all!
