My brother Bernie came over to help so we fabricated a bracket that the pitot and static air pressure manifolds could be mounted to. We riveted the bracket to the firewall and installed the static air pressure manifold. We also connected the input static air pressure tube and routed two of the output static air pressure tubes, one for the AOA system and one to the EFIS/EM display unit. I ran out of #4-40 screws to mount the pitot air presssure manifold so we continued by installing the outside air temperature probe and carrying out its wiring installation. Then we called it a day.
