I wouldn't sell these so fast, unless you already bought and installed new seats in your car.
I had these same bad seats and tried a dozen different custom seats in my car, and none could fit properly and still give enough headroom. I tried them all. maybe the Corvette seats fit, but they were pricey.
For less than that, I got an upholstery guy to copy my design and make an awesome set of seats using the original seat pan, back, headrest and track.
The are incredibly comfortable, fit perfectly and look great. For less than any other seat replacement - including the Corvette seats.
Here are mine before;
