Your right , KC, I had a washer that I did exactly what you have suggested..but, it I guess was to thin and would flex or do something that still allowed it to move. I'm going to do what you stated using some stainless. Since I already have the hole from my washer attempt. I prefer the 3sp ratios, the 4sp hasn't move at all. Probably cause I didn't bugger the treads up or maybe because it has a non-turn on both sides.
