Noticed this white sheath of some sort on the base of my windshield wipers on my 95 gt... I hate the white look and one of them is busted (see pic). I was just curious as to whether or not anyone knew the name of this piece so I can buy new ones that are black, and how to install them? Also, do you guys think back to black will work on the wiper arms or should I take them off and paint them? Thanks!
