Jeff,
Thank you for doing the research and posting the results with a perfect illustration picture and
<b>Porsche part number</b>!!!!!
I remember buying, installing and enjoying these mats back in the day from Scottsdale Porsche.
Absolutely, without-hesitation, hands-down, my favorite "securing" design (with the metal clips and "male-female" 90 degree clip).
IMHO, ever-so-much-better than the "strap" style securing method that can "stretch" and "wave" side-to-side with the obsessive metal seat track "T"s (that threaten to scratch the black finish on the seat tracks during "flashlight" required installation).
I have the "superior" mats you sourced in my 94 RS America (held over from back-in-the-day), with an extra NOS set (that I've been "coddling" since the early 90s), with matching Guards Red "PORSCHE" script for PCA concour events and car shows.
Thanks Again,
Porsche
