I replaced the seat covers front and rear with the kit from Johns Classic Cougar about 10 years ago. It was the light Ivy Gold, I did not replace any of the door panels or interior panels but the seats matched perfectly. The only problem I've had was getting the light gold armrests. Every one I've ordered has been the dark. My biggest regret was not replacing the foam in the seats at the same time and now its starting to come apart. But I've been happy with the kit, easy install and quality was good.
