"O" i should say this too you can put stock SA inner hubgears in a ifs lookout and it will work, but the .048 difference makes it so that you can't put the snap ring on the end of the brf.
that is y boby started makeing a different inner gear for the ifs lookout because if you don't ues the snapring the brf can move in and out whter or not this is a problem i don't konw, i couldn't find bobys posts on pirat about it
