Like stated before, planning is key. With the car and strut at the right ride heights, you need to determine mount points for the control arms. If you look at pics of ART or S&W strut front end kits, you will notice that the frame rails for struts are fairly straight, while c/arm front ends have a huge curve/rise to them. Your lower arm needs to be fairly parallel to the ground, so your mount points are very low.
