It would probably cost less and create less work to have the original box rebuilt. The sector shaft comes out the bottom of the 60-66 gear box, so pitman arm and drag link mods would have to be made. Also some sort of mounting bracket would be needed.
Many street rodders use a Vega box on 30's cars, so that may be a possibility. There are flex joints available to use an aftermarket column. It still would require a drag link and pitman arm to connect to the original steering components.
