Do you remember what year Midget? I would like to chuck the vac into the junk parts box. I will try and set up my Google drive so all can get a look at what went on and is still going on, really wanted to get it driveable before winter we are close but that only applies to grenades and horse shoes.My windscreen does crank out. With the original vacuum wipers, they parked below the screen frame on the cowl. That is, when they worked at all. After converting to electric (I used a motor from a later Midget), they just park at the end of the sweep (on the glass). I have a knob under the dash that I manually move them to the proper park position. There are two little chrome wedge shaped objects on the cowl that sort of lift them off the glass and over the frame.
