Hey, Bob. I'm afraid we don't have any nylon pivot bars. All of our pivot bars are metal, but one of them may still work for you. Before we suggest anything, can you tell me the distance between the tip of the pivot bar and the center of the first hole? Also, do you only use one hole, or do you use both?
I'd prefer metal. As you can see in these attached photos we use 2 screws and the distance from the tip to the center of the first screw hole looks like 31/32"
