Are aftermarket A body upper control arms worth it ?
If the plan is 225/60/15’s up front then offset bushings with stock UCA’s will be fine. You should be able to dial in +3.5* of caster, maybe a bit more. And that will be fine. I prefer a little more than that and I do think it’s beneficial, but it’s not absolutely necessary.
There are quite a few people here running 245’s on the back of 70-72 Dart’s without any significant modifications. You have to get the backspace spot on, but it can be done. @toolmanmike has 255/60/15’s on his Dart
