here is a brake kit you can use on the various mustang ii kits that does not change the width.
ECI 704CK

this kit has aluminum hubs, granada rotors, heavy gm calipers, you could swap wildwood or ssbc lightweight calipers that are gm-sized

it keeps the track width stock, so you would not need wheels with special offset
