Airbag on that car won't go off unless the safing sensor (takes 2 sensors being hit to deploy the airbag)was also hit with the sensor that is behind the left headlight. It would have helped for this type of hit for the bag to go off but there are other ways the car could have taken the hit and only hit that sensor behind the left headlight that could end up hurting someone more than saving them. They worked like they where made to in this case which sucks. Man you had alot of work done to that thing, tubular k member and A arms, 5 lug conversion, looks like upgraded brakes....man glad your ok and sorry to see the stang totaled.
