I plan on insulating my firewall using Fiberfrax, Foil, Tape, fire barrier that was spelled out in past threads ala Dan Horton. RV-14A. Trying to wrap my head around the items that use rivets instead or screws or bolts like the battery box, vent assemblies, cable brackets etc. This will require much longer rivets than specified due to the increased thickness of the new material between the item and firewall. For those that have accomplished this, were you able to find rivets long enough? Did you switch to screws and nut plates? Any pics you have would also be helpful. I dont want to focus on why insulate but how this was delt with.
I have attached a drawing to illustrate this.
