GOLD Star
Note the red stitching on that “all black” knob... (product photos 1 and 2 show this).
But personally, if the red thread bugged me, I’d just black-Sharpie that thread and call it done...
Heresy! Lose the black thread and lose the extra 5Hp gained with the installation of the knob! It's all part of the TRD Mojo.
