1958 auto steering column

[kiwi ragtop]

Hi guys, is there anyone out there that knows where I can get a 58 auto steering column. I have done a 605 saginaw steering conversion {works really well}but I want to retain the horn in its factory position,  because I now have a solid center shaft ,the best thing to do is use a complete 58 set up. Any leads would be very much appreciated
