Recently had my front upper control arms powder coated and am aware they are handed. I hole punched the left one so I could identify it. However, I was wondering what the actual difference is between them as I cannot tell from a quick look. I was wanting to double check I had it right.

AFAIK the main differences are the placement of the bushes in the arms. There is a small 1mm gap (arrowed) between the bush and the arm. There is also

an offset in the arm to the tube. Side by side you can see this at the top of the picture.

This is also shown in the in the leaflet that comes with the Nismo replacement bushes.
