You can access the cage bolt through the lower corners of the firewall. You will see a hole on each lower corner. I broke one of the bolts and had to remove the cage nut itself. I broke the old bolt with a breaker bar and a pipe. I also used an impact socket. I was pulling the frame so I had to get it out. After it finally broke, upon further inspection, it looked to be welded together (rusted), so all the WD40/Liquid Wrench in the world was not going to losen it. I just drilled and tapped the nut. Hope this helps.
