Need upgrade guidance

Do you have a source for the wheels and tires? If you don't, I have five (four corners and a spare) original Rallye 14 inchers with BFG T/As mounted on them which I'm replacing with 15 inch wheels and tires on my Dart. I've upgraded to Right Stuff Detailing four wheel disc conversion kit.
If you're interested I can post photos. Not asking an arm and a leg for them, especially if your budget is tight.
