71 Dodge Dart Swinger in England

Guys, any idea if these would fit my 71 Dart? the PCD seems to be correct but not sure about the width. Ive tried contacting the seller but he didnt understand offset and inset, so couldnt get much useful info. The wheels are only 30 miles from me, but currently my Dart is not road legal. So I cant pop round and try them on.

Anyway all feedback welcome.
