Check with Vintage Wheels. I believe they have adaptors for lugs but not sure if they are 4 or 5 lug. They are great looking wheels and Vintage is supposed to be a great company to work with. For the seats you might check with ERA and see if their seats would work in your car. You might also consider keeping the present seats in case you ever decide you want to "race" the car.
