Does anyone know what size Yokomo turnbuckles are? 4-40 or 3mm threads by any chance?

The Yokomo ones I've purchased have all been 3mm I've also used lunsford ones which are 4-40 which is broadly the same when it comes to screwing into ball joints.

I saw Techno listing their turnbuckles as 4mm then the thread as 3mm and wondered if Yokomo was doing the same thing.
Other possibilities...
CEN:
CQ0310 is a steel 3x25
CQ0313 is a steel 3x52
Integy:
C29050 is a titanium 3x26
C29057 is a titanium 3x52
Schumacher:
640203 is a titanium 3x20
7318 is a titanium 3x53
Acer:
43721226420472 is a titanium 3x24
43638996861176 is a titanium 3x52
Associated:
1418 is a titanium 3x21

Ok.... so I cross-referenced the instructions for a YZ-2T:

- Yokomo YZ-2T copy.JPG (7.49 KiB) Viewed 870 times

- Yokomo YZ-2T copy.JPG (7.49 KiB) Viewed 870 times
Which shows the same "4mm" spec... then I took a caliper to one of the YZ-2T's I've got and the turnbuckle shaft measures out to 2.8mm
...Apparently the US isn't the only one with a standardization problem
