rockcity,
I just bought the stainless ones off of ebay, they haven't been delivered yet. They seemed so simple and heavy duty I decided to try them. I will let you know how they work when I get them. Just looking at the instructions, I don't see how they can't work. I figured it was worth trying. Plus, I like the stainless steel look.
You have to remove the plugs that hold the "pills" in. Remove the pills. Then you need to turn the shifter rails 1/4 turn (can't remember what way...) and pull out.
Obviously, you need to open up the inspection cover and unscrew the set screw on the shifter fork.
