I understand the bushing's effect on alignment and how they have to be the correct thickness. Which is exactly why I need to cut mine in the first place, the back bushing is too thick and pushed the control arm back which threw off the alignment and put strain on the roll pin that you're talking about. My car originally came with two-piece bushings BTW they were just much thinner. I need to cut the front bushing and shorten the sleeve a bit so the nut on the end of the strut rod will screw on far enough (like stock) to insert a cotterpin for safety. And that site I linked has specs on exactly how much to cut to get correct geometry.
