Broken frame from gearbox (not just a crack)

I recently purchased an auto 92 RS w/305. The seller disclosed a leak in the power steering that I did look over. This weekend I was investigating more and noticed the gearbox moved when turning the wheel. After degunking the area I can now see what looks like the gearbox has broken into the frame. There is also a break and deformation in the pinch welds. Can someone confirm that this is what I am seeing? What does this mean for the car and how can it be fixed?

Edit: all my pictures appear to have come out upside down...

Re: Broken frame from gearbox (not just a crack)

Yeah that's all messed up. You need to remove the box and rebuild the area on the frame that's damaged. That means either fabricating a new plate to weld into the frame section or grafting a section in from a doner car.

It's a "common" enough problem.

Fwiw, I'm cutting up a car at the moment, I could cut a check of that part if the frame off if interested.

Its usually caused by hitting a curb side ways hard or while turning and hitting that curb. After the fix, make sure you get a bar that ties both sides together.

That's why the Wonderbar was invented...
