Yowch! Bad break! I had a similar break on a AA column a while back, sorry to inform you it will all have to come out to repair it properly. Is your steering gear box affixed solidly to the frame? Thankfully you have it in a roadster so pulling it out shouldn't take more than a half hour. Once out on the bench you can pull the wheel, remove throttle and spark rods then slide the shaft tube off for repair.
Let us know how it goes, and good luck!
