So do you plan on using your stock steering box, adding power steering ? you said column shift , auto or standard trans.?
Not much in upper colmn to start with. Horn components.
Turn signals if you want the turn signals in the column and don't want the add on type, a lot of trucks did not have turn signals from the factory.
