The instructions say to pin the firewall to Station 1 with two 1/4" bolts... but none of the holes in the firewall are 1/4", they are all 3/16" -- and more confusing, it looks like the fuselage frame holes are 5/16". Before I drill something out and regret it, can someone confirm if we should be drilling 2 of the firewall holes to 1/4"?
