Hello DonB,
I've seen carpet kits offered from kit car companies such as Shell Valley, but these may not fit correctly size and shape wise. Your current carpet set could be used as a template for your desired carpet material though. I have not installed my carpet set but I have installed cut to fit peel and stick heat and sound barrier. There are many products offered such as Hushmat. They have a short video of their product. I even put heat barrier on the under side of the hood to deflect the heat from the engine. Anyway, just a couple of things to consider.
