According to the old Mazdaspeed catalogue the 4.44 is a Miata/FB pinion length and would only fit in an NA diff, so it'd require the special modification like the 5.12 where you graft the Miata/FB pinion gear onto an FC pinion shaft and then it wouldn't fit in a TII rear end.

You might as well use the 5.12 then if you're going to have to modify the pinion.
