I just got my K-Mac adjustable front control arm bushings in the mail, dropped the control arms down today. I'll be taking these puppies for the Benz dealer for the pressing. (I'm afraid of damaging them). According to the directions, the bushings can be inserted in any direction, can someone confirm this for me? I thought there would need to be some position orientation. Has anyone installed these with the supplied extractors? I've pressed in my share of two piece bushings in VW/Audi vehicles, but at $500, I'm admittedly nervous about pressing with a vice...
