Shift Knob - Twist Monkey Wrench - M10 Pitch 1.25 This is a one-off custom shift knob. A nut has been welded to a monkey wrench, polished, and then coated with clear coat to prevent rust. This one has been twist-processed and given a black rust finish. The monkey wrench is a used item, so there may be scratches and dirt. Also, there are small scratches that occurred during polishing, so please refrain from purchasing if you are sensitive to such imperfections. The angle may not align during installation. In that case, please adjust with a double nut or similar method. Please examine the product photos carefully before purchasing.
