Oh no! not another 'What size BB' question!

Yes, I'm afraid so.

What size for Son of Strongarm cranks(from 97/98 Rockhopper)-
going onto 98Stumpy' M2 Pro?

73x?.....Cheers, Matt.

107 or 110mm should do it.

Cheers, was gonna try this sort of size. I've got quite a few 68x's but no 73's to test fit.
