I picked up an 84 k10 yesterday to fix up and probably sell, and the drip rails are missing. They were the screw on kind, the holes are still in the roof. I can't seem to find any being sold for the 73-87. They do sell them for 67-72. All I can find is the chrome molding that goes on them. Anybody have any insight on where I can buy a set? Or do any of you have an old set laying around?
