I agree with Deve, SAVE that lock, they are very rare. I've
been looking for one for ten years and never have run
across one.
You're thinking in the right direction as far as cutting the
J-hook. That's easy to duplicate and no one would know the
difference, even the nut can be duplicated but the lock is
really special. If it's a daily driver and your worried about
getting crap kicked up in it, I'd just coat it with a good
heavy coat of grease once in a while. That would keep the
dirt and water out of it, just wipe it if you needed to
open it.
