Does anybody know what the part number is for a grey leather shift knob (OEM on GTs) for 99-04s? The only one I can find is XR3Z7213BA, but dealers tell me that is black, not grey and they don't have any other part numbers for a grey one. As far as I know, all of the 99-04s used only grey for the knobs and boots, right (whether dark charcoal, med parchment, or med graphite)? Anybody have any idea where I can get a grey leather knob?
