I have a 57 Burb with the old vacuum wipers. As you probably know, they stink. However, I love the action where they both wipe to the center at the same time. So how do I go electric and not change my action, linkage and all of that stuff? Did the electric drive wipers of the 55-59 Chevys have the outside to inside sweep like that, or did they sweep in the same direction? Can I just buy a conversion for them? If so, where, what kit or company, and how much? Do I just need an electric motor of that era? Help me out, I'm truly lost. Bongo
