Bobby,
+1 to what Greg said.
Something I've done for each of my cars is to buy the Ford Color/Trim books for each year model. Inside, you will find actual samples of the fabric used for your car. It's good stuff to have if you find some locally and need to match it up.
There happens to be a 1990 book on eBay as I'm typing this.
