Early A body front end

So, need some help from those that have “been there done that”
Car is 1964 Dart. What big bolt pattern tires and 15 inch wheels for up front with disc brakes? Don’t want to trim fenders. Car is really solid. Using later year Mopar disc brake kit.
I have approx. 9 months to get this ready for my sons Prom next year.
thanks In advance. View attachment 1715940803
I have 15 x6 5x4.5 mopar rally's up front and 15x7 in the back
