What's wrong with this picture Part 2, but much more serious this time.

I know its alot of work but you should replace the whole frame rail if you can. I walked away from a Plymouth Duster a few years back because it had welded 1/4 steel plates over frame rot...on the left front right behind the control arms. But that's another thing if the frame rail goes back that far I think it does all the way to the torsion bar cross member.

Totally agree, but that frame rail was never designed to take the torque that box puts on, what is, - a sheet metal frame.
The replacement would need reinforcement regardless, prob covering that whole section,
It's not going to appear stock, it's gonna look altered.
Good design and workmanship, and skill, will make that look professional.
That's just poor design, - many more of those running around,? - cuz that won't be the only one with that issue, like ford truck frames at the steering box.
