I have a 1982 El Camino that has two colors on the interior. My dash/steering column/steering wheel are a dark charcoal gray. The rest of the interior is mostly a light gray except for the seats. The seats are two colors - light gray with dark charcoal accents. Does this sound like something that is original from the factory? Does anyone else have a two tone interior that they feel is original? I spotted one in the Original Parts Group Catalog (http://www.opgi.com/EC_Cart2.asp?Group=22910&ProdCode=L201440&head=0) with an interior identical to mine. My seats are colored as shown in the picture on that page with light gray and that dark charcoal accenting. I can't find any seat material kits that come with this combination of colors.
