I have a 65 B-body with an automatic trans that I'm switching from a floor shift to a column shift. The new column does not have the lever for the back-up light switch, but I still want the B-U lights to function. Is this as simple as just finding and adding the lever to the column I already have, or do I need a column with different internals? I have the proper switch, just nothing to activate it. The parts manual I have does not show these pieces in an exploded view of the column.
