Rubber or vinyl floor mats

Goodmark Restoration Parts back approximately 12 years ago was reproducing the "over the counter" style rubber mats that were available back in the 60s and 70s. Finding a set of assembly line mats in even good used condition is near impossible. The Goodmark mats featured the logos and correct markings from Chrysler and thus the pricing with license agreements did not allow them to be cost effective to sell.

Legendary offers the four piece individual style rubber mats as a possible solution as others have spoke of. You might want to check with J.C. Whitney to see what they might offer. I know that many of the rubber mats that were sold across the counter back in the day were the same mats that could be purchased though NAPA, Western Auto, J.C. Whitney, etc. back in the day. I have been lucky in finding some of these in the junk yard cars that I have gone through. Some will actually clean up to be usable.
