Is it the K-frame that holds the engine? If so, scape it for a replacement.
If it is the frame rails to the body, rot dependent, go here for some help. http://www.autorust.com/
Can you post a few photos so we can see exactly what's wrong? It will make an informed response that much easier, even though Rumble gave you the correct answers.
well as you can see i never got those pictures. its hard to se unless your under the car any way. the k member is ok, its the driver side frame rail that looks bent.
