K-member at the end of its life?

Well I was driving on the freeway today when all of a sudden the duster started handling wonky and wandering erratically, like if its alignment was off somehow.

After driving back home. I tore into the front suspension.
Yep upper ball joints are gone and the lower balljoints are not looking to good either. (these ball joints are only a year old)
Bushings are ok.
Then I found this gem on the drivers side. This is where the lower control arm spindle goes in to.

SO...

Is it even fixable? Like maybe welding around it or is it even recommended?
Or am I better off getting another K-member?
I know QA1 sells a tubular K-Member for like $600... *ouch*
