The ProCars are too uncomfortable for me. I always use Recaro but when I purchased a car with ProCars the difference was night and day.
While I appreciate the ProCars being less expensive, if you can afford Recaro buy Recaro.
The Recaro seat styles I used in my 65 Fastback were the ones I listed below. The seat in the first link I used in a 65 (recovered in black leather) and then remounted them in a 71 Fastback since they looked great. I then also used the seats in the second link and they also looked great so then I transferred them onto a 70 Fastback. Both of these seats fit the interior well without issues but the upper bolsters come close to the door panels.
Finally, The last link show a Honda S2000 seat I also used and it was very comfortable and they fit the car great. I ended up selling the car with these seats. I made a custom center console and matched the rear seat cover and the whole interior looked awesome.
Just imagine them in the color of your present interior.
