More random parts prep on the firewall…dimpling the brake doubler and firewall itself. For some reason, I take a lot of satisfaction in a simple thing like fitting that little plate.

Dimpling the firewall…gotta make sure that the dimples go the right direction. I wouldn’t be the first builder to screw this up.

Dimpling done…looks good!

I also finished countersinking all the stiffeners on the firewall’s back side. No problems, but no pictures.
