Aftermarket Shift Knob That ACTUALY Fits?

[chefgabe01]

The shift knob on the 2004 GT 6-speed is very deep (like 2" below the threads). All the aftermarket knobs I've found have the threads at the bottom of the knob which causes a 2" gap between the top of the boot and the bottom of the knob. Does anyone know where I can find an aftermarket knob that has this kind of depth?

Thanks!
