Should be OK. You can mount the nutplates from the outside by cutting a
recess, countersinking the nutplate then pop riveting.
Much easier is to fit one of my phenolic firewalls. It fits forward of the
rudder cross tubes so provides a complete closure.
Downside is that it's harder to change the gear elastic. Can be done
though.
