Dave,
It's pretty close, considering our original stuff is 15 years old it's hard to say if it's correct or not but it's probabrly the best you can get. I compared to a none faded area of my original headliner and I'm pretty pleased. Also the headliner board is ABS plastic so that is a big improvement over the stock fiber board and will last for ever.
I got the color samples from CARMotorsport as well and the darker of the two is the one I would have gone for but never heard back from them so got it from Hawks instead.
