A Body upper controll arm problem/question

The owner of the car is "daily driving a beat up 71 Duster" and needs some assistance. I don't believe taking THIS car to a frame shop is in the cards.

And YES, you can compensate caster/camber on the opposite side to help correct a drivability problem on a damaged vehicle. (Band-Aid)

Since no alignment specs have been posted in this thread, how do we know it couldn't be compensated for with caster/camber on the opposite side?
