Step four says to "machine countersink the #30 and #30 holes in the left and right.....to fit the dimples in the firewall side.
I feel like I have had to go much deeper than recommended per the directions. Possibly because of the thicker material...? When I place the flanges on the firewall, there is still a gap and I can not get it to lay tight against the firewall. Visible space between the flange and firewall.
