When I went to an electric motor, the arms and blades flopped around. I studied the situation under the dash and after a while, concluded the one arm was too short. I got brave (or was it stupidity) and cut the arm and put in an adjustable piece with slotted holes.
It worked but I still wouldn't advise anyone to do this. Note I could still adjust the arm to the previous total length.
