rear axle shaft

Hello
I have a HH1 1989 Honda Acty Street and I need to replace/repair my rear axle shaft. I need the measurements and thread pitch of the threads. I was wondering if there is a place to find this out?

Thank you

 

On my 1992 ACTY, The nut size is a 24 mm with 1.5 pitch threads.

 

And here is a link to a thread that gives you lots of great information on changing the rear axle.
