Tire size for a 1974 valiant/dart

i'm going to try 225/60/15....i feel the rear will be ok it's the clearance on the front fenders i'm worried about.
any input?
My 2ยข FWIW: I'm running 235/60-15s on cop car wheels all around. If I had front drum brakes I'd have no problems up front. As it is with BBP DB the tires rub inside the fender under SHARP, bumpy corners. I'm planning on going to 225/60 when it comes time to replace.
