Adapters?

Hi all, I am hoping to be the owner of a 1971 Dodge Dart Swinger this coming Saturday. I have a free set of 17x7 Dodge Charger wheels that I would like to put on the car. After talking with the owner, he stated that the cars disc brakes are original sbp discs. my questions, would you recommend using adapters to make the wheels fit, or would you avoid the adapters. Thank you in advance. :)
