pro 90 seats

has anyone installed these Pro 90 aftermarket seats made by Scat, thay sell them at Jegs , Classic , Speedway Motors, they make high and low back styles,and they look sort of like stock seats, I was just wondering about the fit, I have a set of sport style Scats in my 69 Dart now but for longer rides they get a little hard, my adaptors will fit any of their seats.:glasses7: again just curious if any body has them
