68 Dart 270 tires 205 70 r13 or alternate rims

Hey Everyone, I'm losing my mind looking for tires for my Dart. seems like 13 inch rims aren't very popular. any suggestions where to find 205/70 r13 tires or a 14 inch rim and tire size that will fit the 4 inch lug pattern? don't want to just order blindly online to find they rub. thanks for any suggestions. btw, not looking for anything flashy, just wanna drive. stock steel rims would be just fine.
