The kit from eBay seller "ebStores" comes with a shiny aluminum billet style knob, a new plate, a new shifter, and four longer bolts. The only thing you will need in addition is some grease.
You will either need a new shift knob, or use the one that comes with the kit, as the thread pitch is not the same as the stock knob. The knob that comes with the kit is actually quite nice.
The shifter makes the whole thing sit around 1.5" lower, putting the base of the knob almost level with the surface of the plastic surround. It reduced 1st and 3rd shifts by around an inch, and 2nd and 4th less than .5". The shifter seems to go into first very close to neutral, but second and fourth don't seem much changed.
