Funny that this should come up now, as I just e-mailed Chris (Primer3d @ Etsy and eBay) to finalize making the same cards you're wanting.

I have manual windows, too. Although I planned to keep/store my cards should I ever want to return the car to as stock as possible.

If you can sell for $100 each, you've almost paid for new plastic cards with vinyl and padding from Chris. Good stuff.
