Firewall fastener holes

February 13, 2014 – I drilled all the fastener holes in the firewall to final size, then deburred the firewall itself.

Then I pulled out the C-Frame and started dimpling the firewall.

After I got done making noise, I coutersunk all the attaching angles and fillers so they would fit the firewall dimples. I marked holes that are NOT to be dimpled/countersunk, and marked the sides of the fillers where the countersinks would be.

I deburred and polished all the edges and corners of the firewall parts. Now it’s time to scotchbrite everything and get them ready to alodine and paint.
