Foose 17x8 4.5 bs on 67 Dart ?

Ok- makes sense. I currently have 15x7 cop wheels with 205/60/15 tires on the front and 235/60/15 tires in the rear so those tire/wheel combos work really nice. Now-instead of getting both 15x7 & 15x8 Ansen wheels- I could just make it easy and get all 15x7 sized rims and make it a bit easier.
Say- they do make the American Racing Ansen Sprint in a 17x8 size w/4.5" backspacing. Would that wheel work on my 67 Dart and if I still wanted to go low? If so- what tire would be advised for both front/back? Only reason I ask this is I like your tire chioce on your blue Challenger. They are 17" wheels and just the right amount of rubber. Not too little, not too much. What size are they and would they work on my Dart? I hate to bite off your style but they look really good :-)
