If your existing BB is 124mm, there's a pretty good chance it will work with possible minor adjustments to the limit screws & barrel adjuster.
The offset on the DS may be identical with the difference on the NDS or not. It's a bit of a crap shoot.
Whats the actual "code" on the spindle?
It should be in the form of 3-? with ? being a letter.
