Just did this on my '04 C4S. Went from black (this is summer in Tucson), to a nice medium tan. Hartz cloth in twill, had to reuse the glass window, but fits like a glove... This is my second successful (as far as fit & completeness) top from Auto Top Factory, in the Los Angeles area. Their contact info can be found on ebay. Best top & upholstery shop in Tucson gives their product an A++. $430 to my door and $400 for install. An excellent outcome, again. I'm sure that there's similar suppliers as good, but the drive away price was easy to swallow... Best of Luck,
Andy
