Reinstalling the drop for my t-case(went up another inch and HAD to see if raising it would cancel the vibes until I can get ahold of an SYE) my impact wrench spun one of the welded-in nuts in the frame that the crossmember bolts to. The bolt is in now, but not tight. I think I can get it out, but what then? Short of drilling a pilot hole in the unibody and spot welding it back, is there anything I can do? Appreciate the help.
