I think the factory shift knob for your car was plastic with a simulated leather look. If you have a leather knob that looks like a factory knob then it is most likely an SVT knob. There is also a Cougar leather knob that has a different colored shift indicator plate on top. Is was available on one of the upgraded models, but I don't remember which one.
If you want a factory replacement, the plastic one is less expensive. I've never priced one, but I think the leather one is about $60.00. The leather knob responds to leather treatment, just like the seats and steering wheel. Ocassional use of Lexol, Hide Food, or another similar product will do wonders to help it keep looking good longer.
