I know body mount/bolt questions are played out like an 8 track, but no one here seems to get impatient so here goes..

Got the front firewall ones out, the rear trunk/bumper ones out, working on the middle two. I drilled out all 1,482,785 spot welds on the B-pillar support to remove it and then drilled a hole in the floor to allow me to torch out the existing bolt and weld in a new cage nut. It was a PITA and now I'm left wondering if it is completely necessary to reweld in that B stiffener when I'm done...Also note that I will have an 8 point bar in soon...Thanks!
