There was one gray from 95-98. A new darker gray was added in 99, some say late 1998.
BTW, don't rely solely on the interior code, that is not simply a color code. That code describes the whole interior trim level, plus the color. A Limited model with the exact same color will have a different interior code as a different model, Eddie Bauer etc.
I know about the guys on eBay who insist on the buyer relying only on that code. They are idiots, they pretend to be experts, but they are not. Good luck,
