I've got an 83 300CD that has wheels that look like maybe W124 or W126 type. They have a flat face and are 15 inchers rather than the bundt cake type 14's. My really dumb question, are the things that look like LOOONG bolts really the bolts that hold the wheel on or are they covers that have to be removed prior to removing the real wheel bolts. My car hasn't got the complete set of these long looking things as I can see deep down on a couple of the wheels what looks like typical W123 bolts holding the wheel on. I feel pretty stupid asking this, but would feel much more stupid if I break something just 'cause I'm stupid :-)
