Rear unibody frame independent rear end axle and forward control arms mountings repaired and replaced due to rust out

Rusted unibody frame at rear independent axle mountings and forward control arms. Wondering if anyone has made this repair? If not then I will make the repair on my 1998 Ford Escort ZX-2 Hot Coupe using a expertly built tube frame that I've designed.
Let me know if you want me to post it and video it for others to use. By the way, I have over 37 yrs of automotive and aircraft mechanic experience
