I want to buy a new shifter knob. My car has Overdrive but I never not use it. I am always in OD, I mean. I see UPR has one I like. It is Part #: # 1059-08. It has an additional OD relocation button, Part #: # 1059-11. Would I have to buy the OD button as well? Please tell me if I would need to! Thanks!!
