Automatic Steering Column Issues

[WCHLVR]

Just picked up a 64 LWB Custom with a factory Powerglide. This poor truck has had it's life rang out of it but I looking to give him a new lease on life. Slowly sorting through all the messes made by the previous owners but the steering column baffles me though. It is super loose. The steering shaft, the trim bezel/turn signal housing, as well as the gear select housing all have massive amounts of slop in them. I have had it apart several times but something seems to either be missing or worn out/broken.

Would anyone happen to have some insight into this or maybe a exploded parts diagram I can refer to?

Thank you in advance for any help you can offer!
