Then cut that bracket off and deal with the fuel shut off mount later ,besides creating a better design that wont injure you in a crash. and second whats up with the shoulder strap mount(s), cant figure out what you are doing there either. Just trying to save you some hassle in tech.
Second look , on your chute release arm pivot, turn the bolt around so that the threads are not hanging down in the drivers area, you want the drivers cockpit to be as smooth as possible,no snags or sharp impailers. Been building cars for 35 years trust me on this
