I don't know if you all know that Rubber Queen still makes the mats used as original equipment in GM cars during the mid to late 70s or early 80s. For the TATA guys, they even have it in gray. The only thing is, I don't know who retails them. It is model 6363 shown at the bottom of page 4 of the catalog:

I emailed them asking if they ever considered making them in all of the GM interior colors for the car collector market. We'll see if they answer. I wonder if the restoration parts sellers ever contacted them about doing this.
