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?
