Sam,
This rubber mat was not born with this particular car....however is a true original rubber mat.
This rubber mat belong to me and I was going to use it for my own Post Sedan. But seeing how many original N.O.S. parts Greg was putting in this car...I gave mine to Greg.
Yes I have only seen 3 original Rubber Mats (Don Lightfoot, Ron Norman and The GM Reject Post Sedan). These are very hard to find. Try finding one in Blue or Green.
Dan.
