67 C10 Bent frame?

[charx2]

I bought a C10 few weeks ago and I knew it needed SOME work. It is in need of tires very bad but I noticed that the right wheel stuck out further then the drivers side wheel. Further investigation and I think I have located the problem. The bars? that the axle attaches to i believe are bent. I think one of them is bent but I don't know how to figure out which one is bent or if both are bent. My question is, does anyone know the name of said bar? I took some pictures of it. The truck sits on a air ride system as well. It has a very strong 383 in it and with 3.07 in the rear I can not get any traction. It has 215/65/15 on it so I decided I wanted something much wider but that's when I realized that the wheels are not even. I have already put $500 into misc parts and I have a posi and 3.73 brand new sitting in my room waiting to go in. I was going to wait until I got tires to have them put in. This is my first post but I have been looking around for some time and I know there are some experts here. Please, any ideas or suggestions would be greatly appreciated. This is my first old truck and I am learning how to do all the work (that I can) myself. It is my new found love. Thanks.[IMG]http://i408.photobucket.com/albums/pp165/jchar82/Truck
