Clearance between header and ground ???? 1971 A Body

I think the building is nice but for it to hold up in a hurricane it should have rafter ties. Where I live (on the coast) the vertical studs must have metal straps tying the studs to the floor and the top of the studs should be tied to the rafters. Even the piers on which the buildings sits must have metal ties (to the foundation) to hold the building down during a hurricane. Maybe your regulations are different?? Pics of your car would be nice!!! Treblig
