Repair help needed - Broken frame from dragging jack

https://imgur.com/gallery/lg5RLF1

First 3 pictures are of the back right corner, you can see how far it drops down without it being jacked up into place. 3rd picture is the bracket that holds the jack in place.


In pics 4,5,6, you can see it jacked up into the right spot. That lateral tube is the one I need to fill with the epoxy to get some internal strength back.


In pics 7 and 8, you can see the front and what needs to be done after I get the rear done.

Thanks!
