Have any of you guys ever installed a 2008 Bullitt shift knob on your Mustangs? I have a Bullitt and got a replacement knob for my car (the same as the one that's currently in it since mine was starting to look kind of crummy) and I'd like to get it installed. Is it a simple screw the old one off and screw the new one on, deal? Or do I need to start the thread at a certain point to ensure it lines up correctly? Or is it more complex process than that?
