Do some research. There's a whole thread dedicated to it.
Unfortunately due to the unique and moronic way in which other Golf forums work, which mostly involves shoving your head as far up Chris Eyre's ar
se as possible that thread says nothing about 02J threads, even when Dear Brad asked.
Now Dave and I did our research, practically by test-fitting the 02J shafts but Dear Brad just asked on Chris Eyre's numpty fest.
So, we know through experience that 02J shafts don't fit.
You've said apparently Dear Brad has snapped one, yet I contend he could not have snapped one as they don't fit on a Golf3 wide-track set up, because they're too long.
I think you'll find we're doing enough research ourselves, why don't you run back to shove your head back into somewhere Chris shines his strange light from?
