My 95 LSC has it, but to chrome door handles. You might want to give mopargtx68@aol.com ( think that's it) a yell, it will be easier to replace the whole shifter than just the button.
They started to use the black knob with the chrome button in all 1995 and up models. My 1996 base had one and I just picked up one from a 95 in the junkyard to use on my 94.
