Notice that several shift knobs offered on Mustang sites don't fit 06's. Saw a Sparco Shift knob I really liked but don't know if it will fit. Can anybody refer me to some cools sites that carry knobs that willl fit an 06.
I have theirr shifter ball on my 05 5sp and love it.Feels much more comfortable in my hand than the original.Vader GT said:That's incorrect. 1979-2004 was M12x1.75 (not 1.25).
2005 and 2006 are 1/2-20.
Stangnut --
www.monsterknobs.com says Item #002 fits 2005+, meaning 2005 and 2006.

But then again, I could be completely wrong about everything 

Have the MGW gripper knob and Saleen short shift kit, vast improvement over stock. Nice thing about the MGW knob is it comes with a special adapter to hold the shift boot up.
