Can I cut here? (QA1 upper control arm issue)

Mopar put out a Technical Service Bulletin for the '73 models for a fix if a car suffered from a loss of alignment. The dealer-fix was to weld a gusset on the UCA mounts if cracks were noted.
So "in general" it could be assumed that some reinforcements in this area is recommend, especially when the car is used on a more performance orientated way.
