Off a new TL, its beautiful. It does not bolt on originally so I had it professionally re-threaded to fit. Now it screws in just like stock. Screw old one out, screw new one in, done.

Beautiful knob. Do not know what else it fits but bolts onto Integras just fine. 10 x 1.5 mm thread pitch. Should fit a lot of cars. Asking $35 shipped.
