Sorting out the shifter knob. My truck came with an aftermarket aluminum knob kind of half jammed on. The shifter thread was a little dinged up so I chamfered it. It measured 0.374 and looked like a fine thread so I bought a 3/8-24 nut to test it. Could not tease it on. So I bought a 10M-1.00pitch nut and it fit perfectly. Now to find a knob.

EDIT1: It looks like M10x1.00 might not be a thing, despite the box labeling for the nut. So maybe it's a 1.25mm pitch?

EDIT2: There is an M10x1.00 nut available, but have not yet seen a shifter knob with one available.
