Don, you just keep on waving your magic wand over our 71-73 Kingdom! Most of the used wiper arms I've found in the past few years have had rusty, weak, or red stains where the springs used to be. Also good to see that the 17A504 clip is included on the "Follower" arm. Lot of those were lost over the years as they lost tension or broke and fell off. Another item to place on my want list to Santa!
