I gave up on the ones that were OEM, I had a problem with the windshield wipers being lifted off the windshield in high wind or when a truck would pass.
I went with shorter ones, last ones I purchased were 28". My wipers bolt on, a pain to change but if you find a pair that doesn't have the holes in the right location you can usually drill a hole and make them work. I've done this for the last ~10 years.
