What color red for new 65 Cuda carpet,from Legendary Interiors?

Almost every replacement carpet in North America comes from Auto Custom Carpets. You can find an enormous range of price for the exact same carpet, shipped directly to you from ACC, depending on where you buy it. Suggest you shop around. Me, I've had excellent service and very friendly pricing from www.stockinteriors.com . They (and ACC themselves, too) will happily send you as many 2" x 2" squares of sample carpet as you request, so you can go out and hold them up against the seat, the dash, the exterior, etc. to find your optimal color choice.
