the big fatty **** things, near the top of the rad to hold on the grill. Mine are stuck from rust and age. how do I do it? i'm thining hit it with lossening oil, then srew the litttle screw to the top and pull it out of the bottom. make sense? I can get pics/diagrams.

 

If you mean the "****" in the lower left corner of this photo, it mainly is the adjustable hood bumper, and sets the height of the front corners of the hood. Penetrating oil is the best place to start.
