Got it out finally and starting on the fabrication. Got frame cleaned up and fitted the rectangular tube.
In addition to or in place of welding, I'll attach it to the frame with 2 long bolts through the top of the frame. One in the square hole and another further back. Any reason you didn't...
Repairing my Vue as well. How did you remove the bolt? I was able to cut off the mount and slice through the bolt but it seems to be seized in the bushing. When I turn it from the bottom it just twists the rubber in the bushing.
