This post is more to share information than ask a question. I was having the hardest time finding windshield wiper parts. I had contacted a few of the RV salvage yards to see if they had any of the wiper arms and assemblies that were broken on my RV. I found some, but the cost seemed to be rather high for old wiper parts. Then I stumbled on to Mill Supply, these guys were great and had all the parts that I needed for my wiper plus lots of other parts (new). The cost was about half of what the salvage companies wanted for used parts. Here is the contact info:
