That specific lower shroud was only used on an AMC Spirit or an S-10. Various length shorter versions were used in other applications (pickups, Chevette, 3rd gen F body, Jeep, etc.) and you may not notice the difference since in the Chevrolet, most of the shroud is well under the dash, even at the bottom.
Here is a link to an article I wrote over 20 years ago, about the knowledge I had 10 years earlier. At the left is a link to Steering Column, which may provide you with some information.
I can't quite tell what is hanging out of the side where the shroud was destroyed.
The broken rack you have in your hand is available, but only as a kit. The GM part number for the kit is 7844651. It appears to be the same kit as sold under a Jeep PN 83510055. GM and Jeep both used Saginaw steering columns, so there is a lot of interchangeability of parts.

On the left side of the column, was the pushrod that engages with the ignition switch also bent/damaged? That pushrod will engage with the piece of the rack (in your hand) that is missing.
There will be 2 rods: 1 for the dimmer switch and 1 for the ignition switch.
It has been a while since I had a column apart, but I think the curved rod that is visible is for the dimmer switch.
I am not sure I see the rod that engages with the rack, that connects to the ignition switch (attached to the column next to the dimmer switch).
