I am starting work on the firewall of my RV-9A project. I will be using an O-320 engine, and want to do as much drilling, wiring, etc. as possible before mounting the engine. It seems like there could be some "gottchas" at this step. Any advice relative to the sequence of work or problems with the instructions or drawings? For example, can the piano hinge be installed on the fuse with the engine mount bolted on? I can see some riveting accessibility issues. Thanks.
