The dinette in my 1983 Excella still has the original fabric. (The shelf on the back of the seat near the door is not stock. It was added when I redid the credenza top and dinette table.) The PO recovered the sofa in the front before I got it.
The view rear from the front shows the dinette, including the cloth magazine "rack" on the back: http://airforums.com/photos/showimag...0&userid=17830
A closeup of the added shelf here: http://airforums.com/photos/showimag...0&userid=17830
gives you probably the best look at the fabric color.
