Personally I'd replace the entire assembly. That way you get new ball joints and bushings.

Ours are forged not stamped, I ordered ball joints from rockauto and went with moog greasable joints. You can’t beat the price or like FBM said get the entire upper and lower arm that brings all new rubber. I changed only what I had to change, which was only the upper joint but I did both to get that out of the way.

Some will recommend getting the whole arm, some will say you can press the upper ball joint out and replace. Albeit, it will be more difficult to press the joint out of the old arm. I always get the forged arms. They're pretty much identical to OEM construction and not much more than the entire arm.

Odd the stamped are shown as the premium upper arms. I wonder if they are lighter so less unsprung weight?

I just did the 211K black highway marauder front end this past weekend. I bought new upper control arms, and the OEM ones on the car had a slip on spacer with rubber.
The new control arm came with a washer, yet never said where it fit...
Once i tried to fit the new control arms, they were wayyyyy to wide to fit ok, and then i used the 2 washers to evenly space the control arm. Seems ok, and you should position the control arm upper ball joint to the horizontal position and torque it down.
That way the bushings are in a neutral position and not binding
