These are 6th gen specific. They work on GT, ST, GTS, and probably any LHD foreign models (may work on RHD too, but not sure). They do not include a shift knob, you can re-use your stock one as the threads are the same. here's a pic I took from TWM's website:
I didn't want to open up one of the boxes. But they look like that only it's the color of stainless steel, not black. but color doesn't matter as no one will see it unless you don't have a shift boot. lol
Not hard to install, took me about an hour and a half last night. but I took some breaks and I work slow. lol. all you really need is a phillips head screwdriver, a flat head screwdriver, a hammer and punch, and a ratchet with a 12mm socket. a 6" extension, swivel socket, and pair of needle nose pliers help though.
I'll get a pic of mine installed soon, until then here is a pic of one on somebody else's car:
as you can see
here, they would normally cost $154.95
