There is a slight length difference in lower arm pivot pins so you may need to buy new one or both.
What is a pivot pin?
I called it lower arm pivot pin referring to the short shaft that has lower arm buching pressed on one end, K member and nut on other end.
Side by side comparison will reveal a small difference in lengths which could very well be related to the difference in strut rod lengths.
All of these hardly noticeable differences can create headaches which is why I recommended transplant everything.
