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
Forgot to add too, the upper lowers and spindals from 73 to 76 duster will bolt right on to your car. You only need to use lower ball joint from same year.
