Anybody ever had to straighten your frame?

[Jason71k10]

I'm not sure if my frame is bent or not....the truck was rolled, but i put it back together. I could never really get the same gap on both sides between the back of the cab and the front of the box. seems to drive okay though, and tracks striaght when I take my hands off the wheel while driving.

If it is bent, is worth getting it straightened, or should I just get a new one? It's the original frame(4x4) so I'd like to keep it, but are repaired frames as strong?? Anybody done this? $$?
Thanks guys
