tires and wheels

Ok....I thank all of you for your help. One more time... I have a 1972 Plymouth Valiant and I want to know if this will work....Can I put 15x7 wheels on it with 215 65 R15 tires on it without any problems with turning or clearance. Original size was 14x6. This car has all shoes on all 4 brakes. Also are the wheel lugs all right handed or left handed when you tighten them?

Original rims were not 14x6. There was no such animal for an A body.

They were either 14.5 or 14x5.5 depending on if you had a /6 318 or 340 car.
