how to tell which color interior

[crazyredneck]

Is there any way to tell what color interior came in my truck? Im having a hard time finding the right shade of grey for the truck its a 1990 silverado and anything that i grab seems to be a shade or two lighter. Is there a trim code like on some of the older gm vehicles that tells the color for the interior? I even tried looking up the colors in some of the chip books and in the sherwin williams data base but cant find anything quite the same shade?
thanks
Brett

Check the rpo codes in the glovebox door, there's a database sticky thread in one of the forums here to decode it.
