Wiper Refills Stainless Arm 64 GT

I sure would not recommend damaging original wipers. Merely stated that some times some of them can become loose. They are only 45 year old LOL. Just take one of them to napa and they can find a refill that will fit. If I can find them in the middle of no-were KY I am sure an east coast auto parts store can help you out.
