If you look in the pics both of the rear rails are Rusted out pretty bad, not only around the body mount but down the side and bottom as well. As for the control arm tell me more. I’m interested, and always looking for ideas. Finally, thank you for the compliment!What is the metal like with the rest of the rear rail. Other than the bushing area it doesn't look too bad. I'm disappointing you are welding the upper control arm bracket back on, thought you might be doing something with the front control arm bracket to get rid of the anti dive in these cars. You did a nice job of boxing the frame but for the center (#3) you'll need an access hole to get the bushing in place unless you have some other plan.
