Hi Don, I still have the original vacuum wipers in my 48 daily driver (nonworking), but I have seen complete kits in my truck magazines to replace the existing with an electric. They run about $180.00, but I dont know if they replace the linkage, as well. Hopefully somebody with experience will chime in. Off topic, I am an amature blacksmith my self. I build bits and spurs and do some simple forging to go with that. I love to watch a good blacksmith at work.
