1995-99 and 2001-2003 Auroras? I bought a loaded pair of 1995 Aurora reman calipers. Did not get around to install them. And then traded my 1995 in on a 2001 Aurora.

I know there was at least one change. the original rotors and calipers "1995" were decidedly to small for the car and were upgraded sometime toward the end of "96" I think because I found my "96" Aurora takes the smaller size for the "95"
Its probably safe to say that they won't fit a "2001" model But I'm just guessing

Any dealer or parts house should be able to tell you.
