I have a spare set of later style tan seats, but certainly not new. Why not just go to a local upholsterer and have them recovered the way you want?
Adding a set of wheels you can get modern tires for isn't like cutting the body and modifying. Wipers are usually in the trunk to install if needed, they ride up the windshield. That said I've been caught in downpours and never needed them, just a touch of Rainex.
The guys that don't touch or improve their cars are usually not the ones that love and drive them, more the ones that think they can make a buck as an investment!
