That shim is the caster shim and needs to be installed otherwise the steering wheel will not return to center position. Looks like they may need to be replaced.

That is an ugly weld. I can’t recommend a solution for that hot mess is but I’m sure we’ll have other ‘Bolters with more experience chime in soon. My drivers side was also loose so it’s a common issue. In my case, I reamed the holes for 1/2” grade 8 shoulder bolts and bolted it back on.
