1993 Other Subaru Models sagging back wheels

Tires and Wheels problem
1993 Other Subaru Models All Wheel Drive Manual 100, 00 miles

my husband drove my daughters subaru too fast over railroad tracks. The car bounced and hit bottom.A day after that we smelled burning rubber while driving, then the tire blew. My husband put a donut on and now the back wheels turn outward from thebottom. He says the frame is cracked ( he is NOT a mechanic!) And the car is history. Any hope.
