seat covers 65 dart 270

Im looking for something to simply toss over my seat for right now nothing involved nothing expensive im restoring slowly but the most important things for me at this point is the door locks since well they dont lock since there are no keys for the locks (suggestions needed too), and replacing the wiring which i plan to do this weekend (easy). but as for the seats right now i just need a quick fix so im not sitting on rotten foam and a towel!
