Yes you can use those parts with the MO5 diff, that way you do not have to use blades on the end of the universals.
I also use the 416 diff nut, redrilled and tapped to take a 2.5mm diff screw and change the thrust bearing, to a 6 x 3mm bearing or get a rebuildable thrust bearing.
I only change this so that I can make the diff tight, so that I do not have diffing out when using the 13T BL system we use here in Australia.
The 3Racing Sukara gear oil diff is the incorrect pitch and requires modifying to use properly, unless you just run it in. I have heard of others using modified NT1 gear oil diffs.
Perhaps after TITC 3Racing or Yeah might come out with something. Who knows SPECR have already built a FF03 oil diff, so just a rejigged outer could be on the cards for mini.
I do know that one can be modified very easily to use in a mini, however durability testing is still being conducted. Diff oil weight being tested is 500 000 for more front hook up. At this time he is not willing to share until race proven.
Hopefully one will be released in the future.
