I`m building a site for some car parts. They cover in some cases many different years of cars. Right now I`m writing ie 90-97 Ford parts as my description. In the meta keywords I`m putting the different years ie 90, 91, 92, 93, 94, 95, 96, 97, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997. I`m worried about it being seen as keyword stuffing. But I want the different years since it does cover those years? Thoughts?
