Why spend dough on a crown race he may not need? This thread is rapidly proving my signature line that one measurement is worth 1,000 opinions. We haven't reached 1,000 yet, but we easily could without solving the OP's problem.

The OP needs to measure both the fork crown and the race. That and the info provided here already will tell him all that he needs to know, and without actual measurements no opinion can do any good.

BTW- though the nominal size of a JIS crown is 26.4 the crown seat on the fork should be 26.45 to provide for the correct interference fit. Likewise for JIS, 27.0 nominal, 27.05 actual.
