They are available with two different size spoke holes in the flanges (105g and 80g). So be sure to buy the one that best suits the spokes that you intend to use.
If I were to rip one apart (not going to happen) I'd guess this would work. I forgot about sizing the spokes/flanges, good to know someone is doing my thinking for me.
One issue I had with my old CB as a kid was the axle broke. It was on a Schwinn Scrambler BMX bike I rode of a modified curb ramp. But I'm not planning on doing that again so it's a moot point.
