I got to the same mind as you Chromesux. I replaced it 1 last time. When this one leaks, I'm plugging it with my aluminum bolt (it's an aluminum case after all) and a crush washer or nitrile washer.
I don't really find much use for it anyway as I have gotten in the habit of knowing by speed and pitch of the motor RPM what gear I'm in.
My neutral safety connection was killed long ago, so the switch serves only for the indicator light and seeing that little green light simply isn't worth the $.
