65 Dart Wagon Conversion to a Sedan Delivery

I didn’t really notice it when fitting the seats, but now I notice that the back of both seats are different heights. The passenger seat is from a 66 Dart with stock brackets that bolt to the seat and floor. The driver’s seat is bolted to a power rack from a 68 C Body wagon. Would you do what’s needed to raise the rear of the passenger seat to match the level of the driver’s seat?
