Steering Problem -Need assistance

Of course something else could have loosened up causing the header to drop in the path of the steering arm, but the area around the driver side motor mount would be my first point of interest. Lost or loose bolts, broken insulator, broken or cracked mounting boss, failed K frame weld, anything that would allow the engine to drop.

Get the car up on a drive on four post hoist to inspect it with everything at ride height post haste, that sucker sure doesn't sound drivable the way it is.
