what threading tap?

[nyberg_]

Im looking for a left rotation thread tap for the steering arm on the M8 CF8, it´s the inner one .

any of you guys know what it is I´m looking for?

only thing I´m pretty sure of is that it isn´t millimeters

If its the part I am picturing, it is 3/8-24. So 3/8 fine thread left hand. Maybe a pic of the part for clarity?
