You are probably looking at a very very very low minority considering these seats came out a year ago. If you are really interested, try it out. Your seats may have some electrical connections, but they all detach. See if the seat fits.

 

Put a request in to a national salvage parts system. They can call you when some are available. If you can accept vinyl or leather, you can recolor them to your needs without a lot of trouble, so you don't need to request your color only. Not so easy with cloth-insert seats...

 

Can I assume you measured the width, since you have a prototype available? That will be the biggest factor in making them fit.
