Stef,
I used screws to the firewall, not bolts though the firewall. I did not hinge it, just attached it per plans with the recommended spacing. I see no reason that screws would not be sufficient.

I want to do this with small AN bolts thru the firewall. My problem is...you need very wide hinges not to damage the frame frome the Side wall from the fuselage by instelling the bolts. Or do you all used screws And go in to the Side frame? If you use this methode, you can pre drill it at 10 mm from the Side.
