Does anyone know what the thread size on a 2002 v6 mustang is? I want to buy a custom shift knob that is 2 1/8" but I want to make sure it will fit.

if all else fails, go to the local hardware store and buy a couple different size nuts and try them to see which one fits. Try fine and course threads.

Thats what I planned on doing I was just hoping someone already knew. haha
