69 Dart Swinger Wheels /Tires

So, I bought 7" x 15" Cragar's with 5/4 bolt circle and 245/15 BF Goodrich tires for the rear. I had to back-order 6" x 15" Cragar's 5/4 bolt circle and 205/15 tires for the front. Just received an email saying Cragar is no longer making the 6" x 15" in a 5/4 bolt circle yet it appears they still make a 6" x 14" in that bolt circle. Would it be ok to run 14" on front and 15" on rear or would it look wierd. Also does anyone see a problem with the 245/15 tires on the rear rubbing. All suspension is stock.
