Will 255/60/r15 on 8 in american racing wheels 4 1/2 in bs fit 67 barracuda notchback

Redfastback, you're car sits exactly the way I would like my '67 notchback to sit - more sportscar than drag racer. What front wheel/tire combo are you running?

My concern is the front wheel/tire clearance. I have 205/70-14's on now (don't remember backspacing) & they just rub the subframe at full left lock. I would like to run 15x7's, but it doesn't look possible. Going bigger in any direction seems like it will hit somewhere. Cheers.
