I got those floormats on ebay, you can also find them on a mopar restoration site..I only put them in for show or in this case pictures, I recently Recreated the original mopar oil filter for the 1981 2.2.
I have seen those on eBay lots of times, in fact there should be some on there now. I've seen white ones that say "RELIANT" on them, although I'm not sure his say that, I don't remember.
You come across some neat things by searching "Reliant NOS" on eBay.
