I have 2 sets of these floor mats available. Purchased years ago, but sat on a shelf.
One set was in my 93 Mustang, for about a year and 1000 miles. The other set is brand new, never used, and still has the Ford instruction sheet with it. I recently got ACC blank mats to replace these. Love these mats, but the color difference between ACC Opal and these drove me nuts. I don't have a reference to compare to, but these were stated as being Opal when i purchased them, but they are darker than the ACC Opal carpet in my car.
Part number is F3VZ-6113005-AAW on both, with a LH and RH distinction.
I believe these were Ford accessories available from the dealer at the time.
$200 for both sets shipped FedEx from Auburn Hills, MI. Local pickup/delivery available.
The one pic below shows my new Opal mat compared to these, for a color reference.
