Porter built A Arms and alignment shims

[catch2otwo]

In the process of installing my porterbuilt a arms and realized I didnt know how many shims I pulled out during disassembly. How do I figure out how many shims to put in just for a drive to the alignment shop.

Also on my pb upper control arm, when I tighten the two nyloc nuts, I can see see one bushing isnt quite all the way pushed into the arm. The nuts are on as far as they can go. Is this normal?
