Torn torque boxes?

I recently destroyed the rear end in my car and Im going to be throwing a new one in it very soon. The right axle tube was welded so Im pretty sure the car has led a rough life. Im afraid to look at the torque boxes but I mind as well while Im under there. If I should find theyre cracked or torn is this something i can repair? I have a welder and all the sheetmetal fab tools im just nervous. Also my car is a 92' GT would it have quad shocks?
 
GT or LX makes no difference. They're the same car except for the body kit. And yes, it came from the factory with quads. Any damage that is done can be repaired. A little cutting here, a little bending there, a little welding can fix it right up. You should put upper and lower battle box reinforcements into it along with full length weld in sub frame connectors with the seat brackets.
