Some rain related Dart questions

We're supposed to be getting some rain here in the next few days and the wiper blades on my 1970 Dart are shot. I went to a couple of the auto parts stores and nobody seems to carry the correct Anco style I need. all they had are ugly modern replacements with the arm attached. does anyone here know a source for these blade refills?

P.S. I also am in need of a passenger side splash panel (with gaskets and bolts) for the 70 dart. its that metal piece that prevents dirt from being thrown into the door hinge area. Any help would be greatly appreciated.
