Where did you get your carpet?

When building my son Aaron's Dart Sport a few years ago, we bought a pre-molded carpet set during a car show/swap meet in Ennis, Texas. The vendor was "Trim Parts", if I recall correctly, and they were based out of east Texas somewhere. We are now to the point of needing carpet to complete the interior on his '74 Gold Duster, so I was wanting to know where you have gotten your carpet, and if you would speak on its quality and price.

The Gold Duster has the fold-down rear seat option, so in addition to the molded floor pieces, we also need some extra 80/20 pile carpet to do the rear seat back, trunk divider, and the flat platform behind the seat.

Thanks for any input,
Jerry
