Do you use the prop nut spinner all by itself or does it go on after the old washer and nut? I know it seems like a dumb question but I wondered this when I installed it. I opted to just use the aluminum prop nut spinner by itself to save weight. I saw a pic of one just now that had both installed. Scroll down in the following thread and you'll see it.
