In the front, a 17x9 will be very difficult to accomplish. You need about 6" of backspace to get a 17x9 in the front. The problem is most 17" rims have tie rod end interference issues starting around 5.6" of backspace. That might work with a 275 on a barracuda because the fenders are a little more forgiving than on a Dart, but it would probably require fender rolling.
That's why I run 18's, they clear the tie rod ends because the tie rod actually fits inside an 18" rim. I haven't rolled my fenders, but my 18x9's have about 6.1" of backspace if you correct for a 73+ disk brake set up.
