I asked a while back here on the forum about better windshield blades for my truck as all of the reproduction wiper blades I could find were just not very good. I look everywhere I see wiper blades for 12" blades and I finally spotted some at the local parts store. I got him to order me some arms that they would fit on and now I finally have wipers that are as good as a modern truck. The wiper blades are made by Anco and the part number is 91-12. The wiper arms are adjustable for the length and blade angle. They are also made by Anco. 41-02 is the part number for the arms. If your local parts store can't get them, you can probably do a search and order them on line.
