Ford Focus heat shield fix

I recently noticed some tin-can rattling coming from the underside of my mom’s car. Google'ing pointed me towards the rear heat shield coming loose. I used some aluminum flashing and oversized washers to fasten it back in place.

Tools:

1. Scissors
2. 10mm socket wrench
3. WD-40
4. Framing nail + hammer

Parts:

1. 10-24 nylon lock nuts
2. 3/16" x 1 ¼" washers
3. aluminum flashing
