I have recently completed a restomod 57 Buick Special 2 dr HT. I'm not sure that the wiper arms that were on the car when I originally bought it are the right length and have found conflicting information about wiper arm length and wiper length. Could someone with a 57 check the wiper arm length and the wiper length? or if anyone knows where I could buy new wiper arms and blades that are correct. I have bought several restoration items from Bob's Automobilia but he says his catalogue may not be correct for these as he also has conflicting info. Maybe the windshield is shorter on hard tops than sedans? The rear windows are smaller.
