I was removing my dash and I didn't notice the spacer that has been mentioned in some posts. I did hear it fall down though. Now that I have it back where exactly does it go? I read that it goes on the screw that is under the speaker grill. I'm guessing that means the screw up towards the windshield? Also, just out of curiousity, what is the purpose of the steel cable that runs from a-pillar to a-pillar?
