Wiper blades
Many cars can accommodate longer wipers but 15 is stock. As Mattax pointed out OER/Classic sell the correct refill and blade if you are 68 up (us 67 guys get no respect), K164R is the refill for the red dot type blades. And they are shipping orders as of today (4-6-20)
I wondered if my Dad swapped them out at some time, looks like he did not. KEEPING it OEM!
