I ordered mine from A main lastnight myself. I got the Medium also and can't wait to install it. I liked the Losi 4 shoe clutch and this resembles that with added benefits of easy to remove shoes and spings. That could be a chore in itself with the Losi 4 shoe. I will be honest with you Ron, I liked your other clutch too. That is what is installed on my Mugen right now but when I saw this, I jumped all over it. With the Losi clutch, no matter how I shimmed it or what collet I used I could not get spaced right so that when I tightened down the very last screw the bell sould spin freely or if I did then it wouldn't line up to the spur properly. With your old clutch, no problems and I don't expect any with the new one and am very excited to get it in the mail. I really loved the Losi 4 shoe clutch that much. But that is just me.
