Cutting strut rod bushings for correct geometry?

I don't know if you guys realize that the strutrod bushing locates the control arm to center it on the pin bushing that the torsion bar goes into . The arm should be perfectly square to the pin. Cutitng the strut bushing to make the roll pin fit is a real idiotic way of doing this. They make poly bushings for both early and later struts. Where did you get the measurments telling you how much to cut the front and or rear. These bushings are made to locate the strut with the bushing squeezed to a specific amount guaged by the sleeve. Like I said I had the same problem and I called PST and they sent me the correct bushings. The early bushings do not take a sleeve. They are usually one piece. Moog makes two piece without the sleeve for early cars. One piece are easy to install if you have early bars.
