Looking for chassis like mine

I just bought a 06 4Runner sport. 4th generation. I need some work done on the frame. Was wondering if someone could tell me what other model use the same chassis, as mine? I need to call around, to all the salvage yards.

Whats going on with my Frame isn't a big deal. Both mounts for the rear Upper Control Arm are rotted off @ the frame. Thought it would easier, too fine a matching frame and cut them off and wield them on to my frame. I live in VT, where it's not allowed to wield on a frame. So the job has to be clean so not to raise any flags. Thought this would be my best option.

So to be clear, I need to know what other model toyota have the same chassis, as my 06 4runner sport
