Hey John: Nope definitely a 3.3.3. and it is 12 splines that measure the outside at 20mm. I think I may have a line on them now. I am waiting for the reponses to my questions on some that I found on Ebay. The last time I did this though they landed up not having any in stock. I suggest that if you are like Billy in Chicago and have a couple of them that you hang on to them because they are sort of a rare catch as far as tools go. Whenever I get a freewheel that require extracting off the hub I have to go to the only shop in town that has this tool for them to take it off. It gets to be a hassle. Last time I was there a kid that was just watching the store did not have a clue and I had to tell him where the tool was...it was a little bit embarassing for both of us. Thanks for your help and Happy New Year
