I have a 95 YJ that is white, I painted my grill and a fender with duplicolor chrysler white paint and it matches flawlessly.
My White '93 was the same way, very good color match for being as old as it is! Only "trouble" I had was with the clearcoat. I followed the directions on the Duplicolor can (dry times, etc) and when I cleared it the white turned very yellowish or creamy color. So I ended up sanding it down again and respraying the white, and didn't use any clear this time. Without the clear it matched great.
I wento to a local autobody/PPG auto paint place and had them pull the factory codes and mixes. Banzai Blue Poly when I thought it was patriot blue..little did I know. I have "painted" a few cars and body panels in my time and have found that cutting touch up paint with reducer will generally give you a pretty close if not perfect match for faded paint. I used this exact method when I touched up my doors and some nasty rust spots and it matched perfectly.
