Grant steering wheels/ 67 Dart

Everyone im having a tough time trying to find the Grant steering wheel adapter for a 67 Dart. Up to 66 and 68 up...Puzzled. anyone have a 67 dart with a Grant wheel? are the wheels year specific? My beautiful wife was hoping to get me one for her part on my Dart but the more I read and search the more confused im getting. Hope im not sounding to stupid but really.....it shouldn't be to difficult! Correct? Thanks
