Can you not measure the MC16 ones and compare them to the MC18 ones? I wouldn't swear to it, but I think they are all the same. The front-ends are all interchangeable though, that's for sure, so the bearings are similar.

I've fitted RS250 RWU forks to both an MC21 and an MC16 without changing bearings, MC21SP forks to an R2J, and RS250 USD forks to my MC21. Quite why people mess with other stuff and then multiply their problems with different wheels and discs and spacers and whatnot, is quite beyond me!
