Been working on my 1966 Chrysler for 2 years and decided yesterday to replace the wiper blades. Went to three auto parts stores and told the same thing - "We don't carry that replacement anymore." Need your advice. Can I still get replacement blades someplace? Should I replace the arms and if so, where do I get them? A quick look on the internet indicated the available replacement arms don't fit. Move to Arizona where it does not rain? Thanking you in advance for any advice.
