If these are for your 1995, the only light colors where either Sorrel Brown or Lightstone w/contrasting piping. Either way, the seat frame covers were Sorrel Brown. It's a misnomer because they really aren't very dark brown. As I'm typing this I see that your RRC is Black so you most definitely have the Sorrel Brown interior. Lightstone was only available on Cornish Cream and Brooklands Green RRC's. I have a pair of side seat frame covers in perfect condition. I can send them to you for $40 including shipping. I also have the four trim leatherette pieces that go around the front seats if you need those as well.
If you want the seat frame covers you can PayPal me at email@example.com
and I can get these things out to you right away.
