molded carpet recommendations

I'm looking for recommendations for replacement molded carpet for one off my 1970 Darts. I have one that has 50 years and 85,000 miles on original factory carpets and one that has 5 years and 10,000 miles on replacement loop carpet. The original looks to be in remarkable shape and the replacement is showing wear - as in wear areas where the loop looks more like cut pile! Can anybody recommend carpet that will stand the test of time??? Thanks for your time and attention!
