65 Barracuda steering column shaft question

IMG_1369.JPG We're installing a Magnumforce k-member with rack. I know we have to modify the steering column shaft end to fit the rack .... but if you look at the pic, you can see the column shaft "hanging" in the opening in the firewall (you can move it all over).

Is this "normal" or should there be some support? I'm no expert, but I'm just a bit concerned that nothing supports the shaft from steering wheel to u-joint or Rick connection? Or am I way off?

See pic and build thread as well. Thx!!!
