Steering column help

[Tbruz]

Greetings,
1972 Blazer with manual trans and no tilt.
Decided to replace the aftermarket steering wheel with a stock one.
Used a puller with no issues to remove.
Upon removal; i can feel the exposed part of the steering shaft moving form side to side, about a 1/4" or so.
Replace with stock wheel and play is still there; turn sig and horn work.

As I start to go for a drive and turn the wheel I can hear the horn activating as the wheel moves side to side.

Is there a exploded view of a stock column somewhere?
Is there a bearing up top that I trashed in pulling the non-stock wheel?
Any ideas appreciated.
Thanks,
Tony
