Interior plastic paint

I'm looking for a plastic paint to match the pewter color in my 2000 Silverado. Does anyone have any experience with a brand and part# the is a good match. I need to paint about 8 sq inches, so I 'm reluctant to get a quart mixed at the paint $upply $tore. I'm hoping to find that SEM or Duplicolor or equivalent have a good match.
TIA

regards,
Leon
